Re: Idle Problem
check your air flow sensor and do you have a intake? if so, sometimes the intake causes that which is not a problem. it will happen time to time. As far as the AFS, if you do not know what it is or dont know how to clean it, leave it alone

Re: Idle Problem
when my car warms up it does that as well...drops way down in the idle...and yeah it occassionally feels like it is gonna stall...it hasnt yet, but damn its close...I got the car with an aftermarket cat back on it...is it posible that the lower restriction of the exhaust can cause this problem with a lack of sufficient back pressure?

Re: Idle Problem
it is a problem with your air intake. like trd_sr said clean your MAF sensor, could be a dirty air filter as well

Re: Idle Problem
ya the reason it does that is because a short ram or cold air uses an oil lined filter(unless you use a sponge type filter) causing oil to build up on it thats why its a good thing to clean your maf at least 1 evry other month if you clean and re-spray with oil
