July 15, 201213 yr Ugh.....another problem, this is getting old. 90 leg 2.2 manual 364K miles. so here is the issue, when stopped the car idles between 100rpm-900rpms. Up and down up and down. At one point it did die but started back up. No CEL I have recently replaced Knock sensor, fuel filter, plugs, wires, and PCV. Any thoughts...
July 18, 201213 yr Author throttle position sensor ya that is my next thought, but what to do, replace, adjust?
July 18, 201213 yr try adjusting first if that doesn't fix it than replace with one from a junk yard its like ten bucks. don't buy one new they are over $300 i just priced one. idle problems are usually oxygen sensors from my experience but it wouldn't hurt to try and adjust your tps.
July 18, 201213 yr I'm electrically challanged. So I swap the whole throttle body rather than the sensor.
July 18, 201213 yr Ugh.....another problem, this is getting old. 90 leg 2.2 manual 364K miles. That is some impressive mileage...I'd be feeling my age @ 364K miles/22 years old too. +1 on just replacing the whole TB. Does it idle poorly when started cold - after sitting overnight? If so, it's not the 02 sensor, IMHO, as I've read they don't do anything 'til the car is in closed-loop and @ operating temp. 1. I'd clean out the IAC - don't use WD-40 or something that will leave a residue. I think brake cleaner is best? POST on cleaning. 2. Also, clean the MAF sensor w/MAF-specific cleaner. 3. Coolant sensor, aka CTS - if it's giving faulty readings everything else the ECU controls will be messed up. Does it start OK when cold or crank more than usual? 4. O2 sensor 5. ECU could be bad...but unlikely. 6. Fuel pump GL, Td Edited July 18, 201213 yr by wtdash
July 18, 201213 yr Author ya she has put in the miles...here is another tid bit, it only idles like this once the engine has reached operating temperature.
