Weak Acceleration
I just recently bought a Camaro, and I have noticed that when I accelerate it seems like it takes forever to get up to speed, kind of like it is lagging when I push the gas.
Also not sure if this is the right place to ask this either but it seems like I go through gas like it is nothing. I was at 3/4ths of a tank last night and after driving to work I am at about 1/4th of a tank, I drive about 15 minutes to work roughly 8 miles. Any ideas on what can be wrong with that?

Re: Weak Acceleration
Idk but mine is like that too.....it takes forever to get up to speed. Seems like im in 1st gear for far too long. Maybe a new filter n some tranny oil might do the trick. Idk. I was just about to post something similar to this.

Re: Weak Acceleration
It's cause these are old gutless cars compared to modern cars. Hell my G6 had a 6spd and 260hp haha. That was a family car.
They don't make alot of HP in stock form, and they don't get that good of gas mileage mainly due to needing a tuneup and a carb adjustment. Doing those will help both performance and MPG.

Re: Weak Acceleration
Yeah burning up 1/2 a tank of fuel in sixteen miles is bad. Do a complete tune up.
BTW i have a 305 v8 tpi has no problem getting to 60 mph in a pinch. gets decent gas mileage for a v8 if you stay off the gas pedal.
start with a tune up.

Re: Weak Acceleration
Sounds like a tuneup is in order, if acceleration bothers you that much get some rear end gears with a higher numerical value, or swap in a T56.

Re: Weak Acceleration
It isn't that it bothers me, I just figure it shouldn't take about a minute to get to 60 mph. I would love to do an engine swap though, I just don't know what I could put in it. I want to put an older 350 in it, just not sure about all the specs for it yet.

Re: Weak Acceleration
You can put nearly anything in these cars, they have the room for it. You just may have to custom fabricate a few things for the swap, but there's a lot of swaps that have been done successfully. Also I just noticed you have the V6...No wonder acceleration is bad.

Re: Weak Acceleration
Haha. Yeah, but I don't think it should be as bad as it is. I think it is about 0-60 in about 28 seconds.

Re: Weak Acceleration
That sounds about right, mine is 9 seconds with the 305 and 5 speed and weight reduction.

Re: Weak Acceleration
Wow. I was completely under the impression that it would be a pretty fast acceleration. My friend has a 02 Mustang and it is a V6 as well and stock and it hits 60 in about 8-12 seconds.
Well I guess now my question is; How can I make it faster?

Re: Weak Acceleration
Also if I changed the Fuel pump and strainer and filter at once; would I get a better gas mileage?

Re: Weak Acceleration
That is an 02 though, MUCH newer and MUCH better technology, our generation of Camaro wasn't known for being fast or getting good fuel economy, however your economy does seem somewhat drastic and I don't know what to tell you since I haven't dealt much with fuel issues.
Edit: Just remembered, my mom's subaru was getting bad mpg with bad spark plugs.

Re: Weak Acceleration
I was thinking the spark plugs earlier today too. How often are they supposed to be replaced? They guy I bought the car from didn't say when he changed them or not, but if he changed the relatively recently would it be bad to change them again?

Re: Weak Acceleration
Change the o2 sensor (if it's fuel injected) cap, rotor, plugs, wires, air filter, fuel filter, fresh oil change and whatever else you can find.

Don't just start replacing things, try to actually find the problem first.

Re: Weak Acceleration
Sounds good and pretty simple so far. Also I changed the oil myself and I didn't realize it didn't need the entire bottle; is it bad if there is about 2 ounces more oil then the it should have? Same with the transmission fluid?

Re: Weak Acceleration
Changing the oil and filter will mean you have to put extra in, did you check the level before? same for the transmission.

Re: Weak Acceleration
I didn't plan to randomly change things, that seems like a waste of time if it isn't needed. I did notice on the rotors though that it is pretty rusty on the inside of them, so I want to replace them.
Also when I am at work (I work 8-10 hour intervals) and I get off work and go to start my car it will start up, it takes a few seconds of pushing the gas and turning the key; but then I will put it into gear and go to drive off, it shuts off, just the engine though. So I repeat the process and usually about the 3rd time of starting it and it shutting down it shifts into gear and drives normally. I attribute this to it being cold? But am not sure.

Re: Weak Acceleration
Throttle body cleaner for the rotors? Or for the lack of starting easily?

Throttle body cleaner for the throttle body. My car was having issues starting when it was cold without having to put my foot in it and that fixed it.

Re: Weak Acceleration
I see you updated your info under your screen name. you are seriously wondering why a frickin automatic v6 camaro is slow? My v8 5spd camaro is slow. Gee i wonder what an auto v6 is gonna be like. EVEN SLOWER.
Your car is old. You might have to let it warm up for a minute.

Re: Weak Acceleration
This is the first car I have owned that isn't foreign, my other car is a 240sx and a Gti golf. I didn't think that it was normal for any car to take almost 30 seconds to get to 60 mph.

Re: Weak Acceleration
Both of you, do start with the 02 sensor. That alone will typically cut your MPG in half. And in my '89, it didn't trigger the "Check Engine" light, either. Went from 28 MPG to 19 in a week. Then, second to that, check the cap, rotor, wires, plugs and timing. Weak/late ignition typically affects acceleration more than anything else.

Re: Weak Acceleration
After the complete tune up, do as suggested and check your timing ,that is "important".
"After" you have found the starting problem and the car is running right
bump the timing a few degrees and it will react a little quicker off the line.
Also how far up the stick is the oil and trans. fluid ?

Re: Weak Acceleration
Those are faster and lighter cars from the factory, third gens suffered from emissions and basically required upgrades to be worth much.
