Idling Problems
 

My mate has bought a car from someone i sold it too he had it for year, anyway this is the problem he has with it and was wondering if yous can shed any light to it.

car idles low when the handbrake is realesed but upon pulling back up the idling goes back up.

Car runs fine and doesn hesitate also no warning lights come on.

bump

any ideas could it be the maf sensor if so were is it located and how do u clean it ?

or could i reset the ecu, how is this done.

thanks
