Hi,
Anyone could help me out? regarding wira mmc idling issue.
Problem: Idling, it rev at 800-900. When engine is hot. Rev continuously, 800-900-800-900......aircond ON also same. but not so noticeable.
When occur: After head gasket replacement, and replaced a worn tappet screw.(claimed by workshop that tappet screw cant tightened).
I've adjusted TPS voltage, anything lower than 0.75V, RPM will completely stable, but when aircond ON, RPM drops to 400. (which i dont like).
Then...
