hey guys, im not totally sure which section to put this but i been gettin a funny problem latley, ill be at a stop and when i go to hit the gas, light to smash it, it will bog do nothing might putter then all a sudden roar to life and fly down the road like it should, this has happened while cars have come at me and i dont think its very safe, has anyone had this happen to them and succefully fixed it, im thinking its a promble maybe with my egr or my lock up converter but i donno what else, any help please?

 

anyone??

 

check your fuel pressure. Could be a fuel pump. Check it with the regulator connected to vacuum and rev the engine. Should spike to ~45psi when revved. With the vacuum on at idle should be around 35 psi i think. With it disconnected should be a constant 45 to 50 psi. if not you have a problem with the pump. That was my problem when my pump just wasnt putting out anymore. Then if it is i recommend racetronix kit. excellent stuff.

 

does it have an exhaust leak? my tbi did some thing kinda like that

 

TPS can do that too. Any fault codes?

 

only engine code that i have had is code 32 when i was on the highway. i dont have an exhaust leak. i do want to check my fuel pressure, i have an afpr but i will check it out tommorow morning, is there any way to test out the fuel pump or is it a case of wait and see?

 

my car is doing the exatct same thing at the moment. some days its running good and others its like. BLAH!!
just spudders at the light or whatever.
then bam. your zooming along.
i just checked and i found a code 44. so im playing around with that at the moment.
hopefully its nothing to bad.

 

i halvent had that code but code 44 indicates a lean condition. but i know what u mean it happens to me a lot lately and its not cool when u have cars coming at you in traffic and ur tryin to get out of the way while watching a car come bombing at you. i have a feeling my car is gonna bite me in the *** and need a pump, but at least i know how to do it myself, just a pain. i changed my fuel filter 3 months ago, my injectors are all new, i just have to check my fuel pressure.

 

iv had that happen to me afew times it just spudders along trying to get out of the way. its like COME ON CAR!!!!! GO!!!!
anyways. im hoping i dont have to replace the fuel pump.
i replaced the fuel filter few days ago. didnt help much. new spart plugs. and wires. still no good. if you get your car fixed up let me know.
its being a real pain trying to figure it out.
im hoping i dont have to replace the injectors.
by the way. are the injectors fairly cheap?
if they are i might just go pick some up then if they arnt to expensive.
the fuel pump on the other hand. i have no idea how to replace it. but it looks like a real pain in the butt.

 

i did the ford fuel injectors, were a lot cheaper and work really good, bit bigger there a 24lbs injector, the fords for all 8 were 450 at the dealership as opposed to the gm injectors costing almost 200 a peice and i use to work and a gm dealer and still that pricey

 

holy wow.
i just need 2 lol
i got a 305 TBI engine.
but dang $200 a piece?

 

Really the only way to test the fuel pump is to hook up a pressure guage to the schraeder valve and make sure it is putting out 45 psi or more. A real good test is to leave the guage hooked up while you are driving so that you can see it when the car bogs (preferably not in an intersection, LOL). However, with an aftermarket FPR and Ford injectors 24 lbs, I'd be willing to think maybe it's a case of too rich, which could cause your bogging. If your FPR is adjustable, I'd try going down with the pressure 1 or 2 notches. If the FPR is non-adjustable, I have heard many tales of rich running engines with Ford 24 lb injectors in these cars, everything else being stock.

No, you are lucky josh. TBI injectors are much less than $200. TPI injectors brand-new are $200, for stock 22 lb replacements (on 5.7 L), or so that I've seen. And there are 8 of them...

 

oh ok i was like what?!?!?!
how much are the injectors for a TBI?

 

I have seen them brand new anywhere from $70 to $150 and more if you really wanna drop the coin. A good price if you asked me. I wish sometimes I had the TBI, LOL! TPI is a great system until something breaks, LOL! With proper care however, it is a pretty reliable system (cheap to maintain) and when you start pushing 200K miles as many of us are doing here with the 3rd gens, these things start to happen.

 

yes. mine is almost pushing 300k
275k right now. someone must have been doing alot of driving when i bought it.

thanks for the info.
i maybe pick up some injectors if mine are bad.
they dont seem to bad but you never know.

 

If your motor is running fine, don't worry about it. After 275K, whatever was gonna break has already broken! Congrats on 275K! People like to speak unfavorably of our cars, and to see you run that many miles is a credit to you keeping up on maintenance, as well as the previous owner(s). You have a Bitchin' Camaro in every sense of the word! I just got the OCT issue of Consumer Reports, they are touting owners of cars with greater than 200K miles. You should submit to them your story! That is awesome! They'd never believe you when you tell them what model car you have. Us Third Gen lovers already knew that! My GTA could break down every other mile and I'd still love it! (It wouldn't do that)

 

alright so i checked my fuel pressure and its pretty much bang on with the vacume connected my pressure is 39 - 40 psi and with it off a steady 50 even when i rev it. i did turn it down just a bit and so far its been good, but well find out more soon once i go driving for a while
