High idle RPM's, does it hurt? fix?
 

My car idles around 1100-1200 rpm's and the guy at the nissan stealership told me that it could really hurt the car. On the other hand, the guy at Stage 6 Motorsports told me that it couldn't hurt the car. Anyone know? And if so, how can I get my idle speed fixed back down to normal. thanks

Definately high. My car might idle at 7-800 rpm's. Have you recently had any work done on your car?

too high... time to check it out

If you have an automatic, it puts more stress on the tranny when you are at a complete stop (as the car wants to go faster than at 700-800rpm). If you have a manual, I see no harm as long as it isn't something in need of repair under the hood.

adjust the IACV with a flathead FTW!?

Is this when the engine is warm?

If the idle is that high your check engine light should be on and a code set that likely points to the problem.

only time my idle was that high was after i got a tune up or something when they changed my spark plugs and cleaned my tb. it would idle at like 1100-1200rpm and everytime i turn on the car it'll sound like it's being reved or something =/ and when i'm driving coming to a stop it'll give me a slight jerk before stopping. i brought it to the dealer and they fixed the problem but i don't know what they did tho.

has the car always done this, or is it recent? anything happen that might make be linked to it? aside from the engine.. it's a waste of gas too..

it could be a broken TB...a local 6spd over here has a 1500 idle...and his TB is broken

also Shogunsc4 had similiar high idle problems...and similiar conditions...it turned out to be his TB and MAF
