Friday my car started actin a lil sluggish. I would press the gas halfway down and it would go but when I pressed the pedal ALL the way down it would just go the same speed as if it was halfway down. I know it's a V6 but it's not as fast as it was. Then I looked and saw the Service Engine Soon light came on. Today I took it 2 the place where my trans. got rebuilt and he drove it with me and he said it is shifting fine so he got one of those lil scanners and checked it. Here's my codes...

35 - Idle air control problem
44 - Lean Exhaust
43 - ESC module or sensor circuit problem

Does anyone know what I can do to fix these problems and does anyone think any of them are what is wrong with my car?

well check for the obvious probs, like see if you got a vac hose broke, or something came unplugged, usually you don't just out of the blue get like 3 or more codes. My iroc did that and I had a vac hose broke. So just check around your engine bay for something that looks wrong.

Well... the 35 - Idle air control problem has been that way for a while... when I sit idle like at a red light or something with my ac on then u hear this click about every 5 seconds and it goes up about 200 RPM... like from 1000... to 1200... 1300... dunno why but it does... and then after about 15.. 20 seconds of not goin anywhere the Service Engine Soon light comes on... this guy that is a real close friend of ours is going to look at the car thursday and see what he can do. He said my cat my be clogged or somethin. Hopefully he can fix whatever is wrong...

Well the mechanic we know said it was transmission... transmission place said it was clogged cat... took it 2 exhaust place... they looked... I have no cat! SO... then today I was coming home from school... then the check engine light went off and I noticed it was accelerating like normal??? Maybe trash in the fuel lines? I put some injector cleaner and some gas treatment stuff when I filled up 2 days ago. Maybe that helped? Or maybe my timing is messed up? Anyone?

Well... the light went off... then it came on... off... on... off... on... etc... Does anyone know what my problem could be?

35 - Idle air control problem
44 - Lean Exhaust
43 - ESC module or sensor circuit problem

those are the codes I got that day and the Idle air control problem is something with my ac. The lean exhaust the guy said it was because I had no cat. What is Code 43? That ESC module or sensor circuit problem? Anyone know what that is and if that could be causing my acceleration problem?? Please help!

well i m fighting the 43 right now, it should be your ignition module, its located under your distur. cover. Check to see if the connectors are plugged in. I got a L98 but it should be the same on yours. Now the lean exhaust, I don't think that would be caused because you don't have a cat, on my 89 RS 2.8 I had back in highschool, I hollowed the cat out cause it got clogged and never had a prob or got a code. Let me check in my manuel and I get back with you about that one.

I just checked in the book, look code 44 is you O2 sensor, chances are that its bad if you haven't replaced it. Now your IAC well the best thing to do is to take off your throttle body and remove your IAC and get some carb cleaner and spray and scrap clean your IAC and your Throttle body. That should take care of that. Yeah try those and let us know how everything works. hope that this helps.

thanks a lot man... i'll get that looked at tomorrow if it quits rainin... if it's not one thing it's another... power window motor on passenger side is SCREWED... if i shut the door.. window just falls down... the motor hasn't been workin for months now... fixin 2 put the OTHER red door from the firebird on and get it sanded and primed here in the next few weeks... lucky me...
