I have a 1994 Cadillac Eldorado and every time i start it the car has rough Idle and the Idle fluctuate's. I also can feel it in the gas pedal when the car is doing this I tried replacing the throttle body sensor but it still does it I also was told it was the Idle error sensor. So instead of spending the unecessary money again I thought I would go online and see if anyone could help me with this problem.

When you take your battery out and put a new one in all your computer controls have to be reset. You need to drive the car at 55 MPH for 2 min or so, stop, go through normal drive cycle, stop and go and then if it don't straighten out you need to clean the throttle body and the idle air control valve. Hope this helps. PHil

Try cleaning the Mass Airflow (MAF) Sensor. My 2002 Protege check engine light came on and it started stalling at stoplights if I didn't keep the engine revved a little. Manager at AutoZone checked the computer code for the light (P0171?), and it said it was running lean. He suggested I try the MAF sensor cleaner they have ($6.99) rather than replacing the 02 sensor, etc.; it made a *significant* difference. (I think I need to do it again to get it totally cleaned out, but the can is for at least 4 cleanings.) The MAF sensor is the large component that air goes through right after the air filter. If you don't have the repair manual for the car (search online for PDF's), you search for the part online to see what it looks like. Mainly, it's a tube about 4" across with some small wire things inside. The cleaner can said it was a 10 minute job; mine took 20 minutes, but only because the tube leading from the MAF sensor to whatever is next (a kind of bent elbow tube, with a couple of accordian-style ripples) tore, and I had to duct-tape that up to seal it. (Still haven't gotten that replaced - found them online for ~$40. Maybe this weekend...)
