Without any A/C and the car is in park or neutral it idles at about 700RPM which is fairly ok I think.
However, if u put it in drive and hold on the brakes like at a stoplight for instance then the idle drops to like 500RPM after about 5 seconds. At this point the car starts to vibrate which I figure is from the engine shuddering under the low RPM
If u put on the A/C it raises the RPM back up to 700 but as the A/C cycles and cuts off then it will drop back to 500RPM.
So can u please advise what is causing the idle to drop to 500RPM when the stopping at stoplights and car is still in drive? There are no error codes showing up when scanned using a OBDii and also the engine check light never came on.
have the same problem?
