i have a 2k2
ok, i felt my car is very hesitate today. When i first started the car this morning, seems like the car wasn't willing to start but the "fire up" sound is normal, not like you have a bad battery or something. so i started to drive...when i brake...the car seems really hesitate when it about to stop...

Ok now comes the werid problem....everytime when the gear is on P or N....the rpm just goes up and down by itself between 1k and 2k...but when it's in D, everything is normal...

then afterwards, when i left my car for a good 5-10 mins...the car wouldn't start....but..3-4 hrs later....it started again....still have the rpm up and down problem between 1k and 2k

what's the problem??? might be the distributor?? or spark plugs??

 

Could be a faulty MAF sensor.....the car has coil packs, so there really isnt a distributor.

 

Very early symptoms of Idle Air Control Valve failure. Have it looked at. Eventually you'll get a code telling you your IAVC is shot. I know someone who has this right now, and his problem started out like yours and progressed. I doubt it's the MAF, because the car will go into limp-mode and you'll feel like a turtle trying to bring the needle past 3000RPM.

 

My 2k3 had some of those same problems - Dealer replaced the ECM and the ETC Actuator. Still the transmission doesn't seem right, but since I'm over the 36,000 miles - I'm not taking it in........

 

do you know the estimated cost of replacing the ECM and ETC actuator?

 

It was covered under warranty so I don't really know......

 

What is that on your bumper??
