I am experiencing high idle at around 900-950rpm. I have already tried adjusting it using the idle adjustment screw. I recently changed the oil, and I thoroughly cleaned my IAC. I haven't attempted cleaning my PCV or checking my spark plugs, or changing my fuel filter, but the car runs perfectly fine(not sluggish, good gas mileage) when driving. I also have a new air filter. If someone can relate to this or can relay me to a previous thread, it would be much appreciated.

My idle on my Max is the same as yours. I took my car to the dealer, and they said it was fine.

Mine used to idle around 600 before I cleaned the throtle body. Now it's around 750-800.

I don't know why yours idles like that.

Mine does that too, but i think it is cause it is converted.

Thanks for the replies, I feel better now that my Max ain't sick no more.

So, what was the problem? it was the pcv valve, wasn't it? that's what it was when my car idled at 1100 at red lights.

lol, nothing was wrong with it for the PCV valve to be fixing the problem

Paonessa

then it was coincidental.

After cleaning the IACV you NEED to reset your ECU...the computer is still spitting out the same info to the IACV in how to keep it at idle and its f-ed up now cause its used to all the gunk that was in there before...reset it even if you dont have a CEL and it will be back to normal, trust me...

i have a high idol problem. in gear its around 1k-1200 and when in park or neutral its about 1600-2k. it really P*sses me off because its hard to break when you car is opposing the breaks by idoling higher, i dont know what the problem is, and i havnt had time to get to the dealer for them to fix it, it occurs here and there like 2 times a day.

mine can be like that once in a while, when its idoling normal, but when it gets all screwy it shoots up like im reving it and will stay at around 1100 in d,r,1,2 and in P,N it will hit almost 2k

how do you clean the IAC & where is it located at? i search and can't find anything on this. a picture illustration or a website with instruction would be great. thanks.

tvn_1010

oops... i found the instruction under the faq


but are there any picture illustration on the instruction. i am not sure what the IAC looks like, picture wise. thanks.

If you cannot get the idle down by turning the adjustment screw on the bypass for the IACV, then your next step is to adjust the default throttle stop screw slightly.

An idle speed of 900 RPM's is to high. It should idle around 750 in neutral or park.

Disconnect the TPS sensor, start the car and adjust the throttle plate stop screw until you get the correct idle speed. (~750)

Reconnect the TPS and start the car. Your idle should be correct.

If after you set the throttle stop screw your idle is still to high, then try bringing it down by adjusting the air bypass on the IACV once again.

AssyrianRacer

Did you get your car like that or it did it it self, I heard from somewhere that a healthy engine is around 5-750 rpms idle, take in to the shop, or maybe your injectors need cleanging(Or Maintenance)

Why are some of you talking about autos when the topic is high idle with 5sp?

Paonessa

cuz an automatic still idles. maybe the problem's universal
