Where are you located? There are lots of 3.4s here in central Florida...

I can point you to some if you need the help!

Just simply changing the engine to a 3.4L will not improve your milage. If you're getting 10mpg now and all you do is swap out a block, then you'll get worse milage after the swap.

If you're thinking of dropping in a 3.8L out of a 95+ then you have a lot more work to do to get it installed and running.

i want to swap the entire engine and how will that make my mileage worse? the 3.4's are more efficient than the 3.1

grimmcs

The 3.4 got about 19/28(+/-) and the 1992 3.1 got 19/27(+/-). I would have to say that if you are getting 10 MPG than there is something wrong with your engine, and I would look into getting your MPG back rather than droping a whole new engine for +1 MPG on the highway. <-- And youll only get that if you swap over the whole engine/ECM/IGN.

ckyfreak2010

yeah i get 127 miles to the tank.... and 92's on get about 18 mpg from the factory on the highway

grimmcs

iTrader: (1)

I know that when my 3.1 was running I would get 18 city. I didnt take it much on the highway but Ive gotten 24-25 one time.
Are you running rich at all? Do you smell gas when the car is idleing? It just sounds like there is something wrong with your car that is causing such bad gas mileage.

Hey man where do you live at. I have a 2.8 which i could make a killer deal. here is the post i made here for it. https://www.thirdgen.org/forums/engi...er-engine.html

id say you need to start looking at what DTCs are stored, is there a vacuum leak, any sensors reading incorrectly, bad injectors, etc etc. replacing your engine wont help. get a scantool hooked up on that thing and see whats going on, thats the best place to start.

ckyfreak2010

how would changing my injectors help but not swapping the engine

My daily driver is a 99 3.8 V6 Camaro....wow i love that car peppy as hell and looks nice, bout 25-30 mpg depending on if im in the city or goin to dallas and back, best ive got was 32mpg to plano to see my gf....thought it was gonna suck having a v6 but man i love that car...get a 3800 if u are gonna swap any and go witht the 4l60e with it... u can probably beat up on some 305 cars with it.... good luck..

drdave88

iTrader: (3)

if your goal is to get another engine then go ahead, i was simply trying to tell you that you may not need to go to that extreme if youre only trying to fix your mileage. and yes if you swap your engine, youll have to swap injectors, so IF the injectors are the problem then it would help. but would you really wanna drop hundreds of dollars swapping an engine only to find out that, oops, i still have the same problem?

and swapping a 3800, nightmare going into these cars, do a search for this by project85, he did this, not a good time. 3.4 is the easy swap.

ckyfreak2010

yeah i want the 3.4 since every one says its easier and haha my grandfather is helpen out with this swap so idc if its hundreds of dollars....anyone know where i can find a decent 3.4?

From reading the exchange in this other thread you created, I'd have to assume an engine swap is far beyond your capabilities.

Let's get down to brass tacks... First, if you're getting 10mpg now, you're either driving like a jackass and letting your car idle for long periods of time, or you've got a problem. The 3.4 swap here is recommended for increasing power while keeping the stock engine management and fuel injection, etc. Converting to the system used on the 93-up 3.4 is going to be really far outside your skill set if you don't even know that your current engine is MPFI not TBI. If you just swap the long block from the 3.1 to a 3.4 you'll have the same problem you have now. Unless the engine has a mechanical problem you're replacing parts with virtually the same parts. A 3.8 swap would be right in line with converting to the SFI of the 3.4, well outside of your skill set. You need to drop back to basics and figure out why you're getting such bad mileage now, and fix that first before you move on to increasing the power. Chances are your car is undrivably slow because of the problem causing your rich condition.

ckyfreak2010

thats why i want to swap the engine but the entire engine not just the block...like it would be nice ot find a wrecked 94 camaro or somthin then take the engine out....and i dont drive like a jackass and i have no cllue whate the probelm could be and if i swap it im have na shop do it

Sounds like a plan if you want to spend 3 times the book value of your car on an engine swap. You'll shoot your eye out kid.

I know its hard to swallow but sometimes things are just outta your ability its best to know what you can and cant do it will save you alot of money and heartache in the long run....i have kids in my automotive engines class that couldnt even do this swap (frankly most of them are idiots in love with hondas that i thought were gonna die when my teacher explained why 4 bangers are generally not good for performance engines lol but i digress) just save yourself the hassle and take your car to a good reputable mechanic and spend your money having them fix the motor youve got.....

grimmcs

iTrader: (1)

Yeah I dont understand why you would want to swap out the entire engine because youre getting bad mileage. You realize that the culprit could be a couple sensors that could be bad? I would rather spend $50-100(a guesstimate)on a couple replacement parts than spending $400 for the engine plus an additional $3,000-5,000(more guestimating) for a shop to swap the engine in...and then find out that your MPG is the same. Mabye Im just crazy

ckyfreak2010

yeah you guys are making sense but i dont see what sensor it could be i mean it runs fine its not slow it just sucks down gas and i dont wanna swap it just for millage i want the few extra pony as well and now im considering a 305 but if maybe i should just take it to a shop... my brother works in a car shop but they "only work on imports" and he says they wont even look at it but they should business is business and i dont think imports are that much different than domestics other than the number of cylinders...but hey what do i know im 16 years old and thats why im asking you guys for help.... so if theys any signs of what sensors could be bad let me know please :-)

grimmcs

Well, how is the car running? Does it run smooth? Irratic Idle? Are you throwing any codes? You might want to check the injectors.

ckyfreak2010

iactually yesterday i started my car and for about 3 mins it was really shakey...i dont no if its becuase i hadnt started it for a week or becuase somesthing is wrong.....i also smel la little bit of gas when it idles..when it was shaking it was doing it idling and driving.....so maby it is my injectors but i dont know much thats why im what do you think that shaking was.....and i get rich and lean mixed up and maybe that could be the case as well....

thanks for all your help

backgammon7

mine did the same thing,but i didn't smell gas. Then it died and hasn't started in a year. I can't figure out what is wrong with it.(haven't had the $$ to take it to a shop) I get the "check engine light" but only code 12 flashes.

_________________________________________________________________

P.S. im not trying to steal your thread. i thought i might have the same problem as you just maybe more severe.

grimmcs

iTrader: (1)

Well if you can smell gas, that is not good. I would check your fuel pressure first to see if you might be leaking some. You can get a gauge like this for a local parts store...

Than check the fuel pressure by hooking it up to the nozzel on the fuel rail. Im not 100% on what the PSI should be, so Ill let someone else chime in with the numbers.

drdave88

iTrader: (3)

Mine sits all winter long w/o being started for at least a month at a time and fires right up. you definitely have a problem, and especially if youre smalling gas!!! fix whatever you need to that wouldnt be included in an engine swap (if youre going to go that route) and leave the rest for a swap if youre gonna do that. otherwise fix it all and get her running right.

ckyfreak2010

i was thinken now since everyone is sayen dont do the swap take it to a shop and see what they think like if its a sensor or my injectors or somthin and then get performance injectors... would that be logical to do?

402 GTA

Fuel Pressure Regulator. Leaking injector. Could be either sticking open or the body of the injector could be leaking. Maybe do a compression test too.
----------
Don't overlook the ignition system either. Check for adequate spark.

If you want to fix your problem (strongly suggested), start by creating a new thread and specify any symptoms. Also do a visual inspection. Look for obvious problems like burned plug wires, and leaking injectors, etc. Get a paperclip and check the codes, post them in your new thread so we can tell you what to check. Just work through it, an engine swap is 1000 times more difficult, cause when you get that engine installed you'll probably have problems like this you'll have to diagnose and fix.

thirdgenfcarnut

Grimmcs is 100% right. This fuel pressure gauge was the best $25 I spent. You will be able to determine any leak in the liquid portion of the fuel system.

Fuel pressure should be 40 - 47 psi when ignition key is turned on, engine off
With engine running pressure will drop 3 - 10 psi

Also get yourself a set of plastic hose pinching pliers.
Fuel pressure should reach about 40 - 47 psi while the pump is priming, then hold steady once it shuts off. If the pressure drops, you have a leak somewhere. Use the hose pinch pliers to pinch off your feed and then your return lines. This will help you isolate your leak.

Alright, if you're 16 and don't know much, than either have someone look at it for you, or have someone who knows what they are doing help you. NO GUESSING!!! Plus, you better listen to these guys, they probably know more about cars at this point than you and/or I will ever know. Don't do an engine swap, it's too costly and much more of a great pain in the @$$ than it's worth unless you get a properly working engine of the same exact type. And just forget about putting a 305 in it unless you like paying for your gas. I don't care what ANYONE says, it will NOT get better mileage than the V-6. PERIOD!

Secondly, they are right. It can be any number of sensors, injectors,
or a combination of them. But changing these will not ONLY improve mileage, it will give it more pep b/c it will be running properly and it will be SO much easier AND cheaper than a swap of ANY kind. And that's that!

Just don't get your head stuck on there is so much more wrong than there really is. Just take a step back and see the WHOLE picture. And ESPECIALLY don't get stuck on wanting to do a swap. It's always better to get the smaller engine working properly for better mileage and to do so for cheaper than getting a bigger engine (unless your racing it) b/c all its going to do is be much more of a hassle than it's worth and give nothing but countless headaches.

Just listen to these guys, get a Haynes and/or a Chiltons manual and it will all work out in the end. Best of luck to you and rest assured that there will be much help on here for you if need be.
