Strange "chugging" feeling.

[Amish_kid]

I'm really stumped on this. My car whenever the engine is warm (no problems at all with a cold engine) if I either try to pull away at any lower than 2.5k it feels as if it is going to shit it's pants and sputters like hell. Other problem which is pretty much I know is the same problem when I'm driving if I let the rpm's fall under 2.8k or so it starts to chug like crazy but it only happens under slow to moderate acceleration if I put it down over half throttle it won't do it. Feels as if the engine is starved for fuel. Also I have replaced all ignition parts(cap, rotor, plugs wires) so that pretty much gets ruled out. If anyone has any idea's whatsoever I'm willing to try anything. BTW is a 91 rs

Thanks!!!1

do you have a cai??

Nopers car is 100% stock

a couple things come to mind. and these are all problems i had.

1. check your exhaust system for small holes--fumes coming out of anywhere other than your tailpipe--you're losing back pressure.
2. check your intake set up--tb, cable, hose, housing. check to make sure everything is as it should be and that there is nothing causing blockage.
3. try taking out the resonator (if you're teg has one) below the airbox.

Ok will do

do you think you could have gotten bad gas? or when was the last time your fuel filter was changed? or a tune up done? does it do this all the time or periodically? is your coolant level full? <--believe it or not this can be a problem.

[gismo0184]

it can really be any number of things, just check what we've listed and if you still can't figure it out--might be time to go to the shop.

Bad gas - Nope
Fuel Filter was changed before I got the car

I've heard from some people that the o2 sensor on the 90-91's can cause that to happen. And from what other people said it did only happen to them at operational temp. So would it hurt my car if I just unplugged it to see if that might be the case. I know it'll probably run rich just wondering if anything bad can come of it.

Lucky
Wow!
Gee Golly Gosh I Must Be.

I have no time for this childish shit you're trying to start. Go look for a fight somewhere else "keyboard warrior".

I'm still trying to find the problem with my car, so if you're not going to help out just keep moving along.

[crazy_canuck]

I'm guessing its a problem somewhere along the exhaust manifold or exhaust system.....how long has it lasted?

[knorwj]

knock it off guys come on, do we relly need this?


ok anyway abck to the car, does it sound like your exhaust is kinda gurgleing? and is there a lack of power? I'm having similar problems with my car lately and I just ordered a bunch of tune up stuff friday so if any of them fix it i'll let ya know monday or tuesday.

[Amish_kid]

Shouldn't be any problems with the exhaust I know there is a pinhole in the muffler itself. But everything else is pretty much new(read no older than 1 year) with the exception of the manifold. Only 1 thing I can think of now and that would be the o2 sensor I can't find one around here til monday and with my luck I won't have one til next weekend ARRRRRGH!!
