Hi, Guys, I just got my new 06 Forenza 2 months ago and I loved this car except that something is unusual with the idle speed. When I start the engine first time everyday, the idle speed will "jump" somehow like 1500-1000-1500-900 and this jumping will last for about 30 seconds. Has anybody else here met simillar situations? What might be the cause? Any suggestions?
If it's only on first start and it's a brand new car, I would first try resetting the ECU. If that doesn't do it, go right to service. They'll probably ask you to leave it overnight, or at least until the engine is cold enough for it to happen again..
happens to mine when cold, but im used to it mostly because my last car did the same, i always just thought it was the car getting itself up to temp. also my fiance's new yaris does the same for a couple of seconds when first start up. my question is does it also do this when you come to a stop with the a/c on?
