|trinitismom09||i am needing some help :( i have been dealing with my car idling high for many months. It idles high when i crank it at times and i kill it and re crank it and it is fine. It also idles high at times while driving down the road and when i go to stop my car it struggles to stop because of the idling problem. I have replaced the ideal air control valve and also another part and it has not fixed the problem. help what can i do to fix this it scares me when my car struggles to stop|

I fixed it, the problem was that my camshaft was chipped in one of the corners. I'm guessing this happened because of the timing belt being incorrectly installed.
All the other parts (IACV, TPS, etc.) had nothing to do with my problem.

This also happens to me. The only thing different is, sometimes it does not happen without load. Meaning, when I rev it on neutral, this does not happen.
The theory about not having enough juice pumping into the battery at idle Did anybody test the voltage when the idle is high, then when the idle goes down to normal level, check if the voltage is the same? This is the first time I've read about this and will be testing it myself this weekend.

|Fletchnutz||I replaced my torn PCV hose last night (typical around 100k miles) and the check engine light went off at first. For some reason though when I start the engine cold it revs up for about 4-5 seconds now and the check engine light comes back on. If it is already at operating temp and I unplug-replug the battery the light doesn't come back on until I leave it sit for a few hours and start it again. After the initial start up it's running as smooth as it ever has and idles perfectly. Any ideas? Never mind problem is resolved|

|Infernal01||Mechanics found that my camshaft is broken, also the timing belt is not properly set. Gonna change that next week and will post here again if it solved my problem.|

I can't find any smoke test here where i live, but i did have it tested for air leaks, none found.
I also cleaned and checked my injectors, they are fine.
A found a mechanic that told me the problem could come from my timing belt. When i bought the car, i changed the timing belt with an amateur mechanic that didn't seem to do a very good job. Can this be the root of my problem ?

|silver zx3||I'll be following this as well. My 01 ZX3 does something very similar, when i stop, sometimes it hits around 1500 RPM and then almost bogs out the engine because it goes back down closer to 500 RPM. I'm talking to some buddies at work and checking with my pops today. A vacuum leak does seem like a probable issue for my car and yours. I'll see if i can find a place that can do a smoke test on mine. If you can end up getting it fixed, then post what you needed to do, that would be awesome! Thank you to everyone's input in here|
