Crazy Idling??? Need your help guys
Alright, my bi-polar car is po'ing me...
Anyways. When I initially start my car, the RPMS jump up to .9k. It stays there for a while, then slowly goes back to .6k.
The car has hesitation, once started, If I WOT the engine, it bogs down, and turds out. You have to feather it, until the engine temp reaches 150 degrees, then the hesitation is gone. But not completely gone, it is still there.
Say I stop at a red-light, well, the car will idle a bit crazy, going from .5k to .6k to .7k. Just cycling like that. A weird sound will be made in my rear, and a light buz feeling will be caused. It only lasts a second or too.
My car has a very noticeable gas smell when I first start it.
When temp reaches 180+ degrees, I will floor it(or 3/4 throttle), it will go fine but once it gets to 2.7k till about 3.4k it stutters, and doesn't want to go to a smooth running. It also makes a popping noise. (running rich?)
Please guys help me out here. I hope most of this is fixable, either that, or its back in the shop and big buxx to be spent...:(

could be, you have a vacuum leak somewhere, that could be whats causing your idle to be erratic, could also be your throttle body is going bad, but doubtful, also check your throttle position sensor, that could contribute to your lost performance at w.o.t.
electically, you have something that is staying on and draining your battery, what i do not know. an auto electric place could help but if it isn't real bad just keep a .2 battery charge on it when it sits in the garage to combat the drain.
Good luck

Pick up a cheap vac gauge, hook it up the the plenum with a "T" and start checking all vac lines. Under/behind the plenum and those running along the left inner fender well to the vac cannister and the gas tank vent system.
A DMM from Radio Shack will help you isolate the battery drain. Pull the +bat lead, hook up the meter and pull the fuses one-by-one till the resistance jumps up (the ECM, clock, etc will have some draw even with the key Off).

PS: I heard that alot of carbon builds up in the plenium, the IAC, the TB.
Would this effect performance, idling?
Also whats this about a machine at local pep boys, or jiffy lube, that cleans it out??? How does it work?
