After driving my car for a few miles and stop some place the rpm is normal for idling. It works great until I put it in park and sit for a few seconds with the engine running.. RPM is normal idling and then suddenly drops and almost dies.
Something takes over and it goes up to about 1400 rpm and the rpm drops right back down. Like a serging thing. Up and down. It may go to normal or maybe all the way down and die.
It usually doesn’t die but sort of goes up and back down. About 1400 RPM and drops back. To normal idle rpm’s.
None of this happens if it is in drive and I am just sitting there with the car. RPM stays normal idle! In drive or any other setting with a load on it but P or N and it starts the looping thing.
Anyone have a clue?
