| | 1992 BMW 316i idle issues
Here receantly I had to do a bit of work to my car. I had to replace the water pump thermo stat and raidiator. About a week after I did all the work the idle started to act up. When the car is cold the motor will run very ruff. Like it is missing on a cylinder. But after a minuet of running it will smooth right out like its supposed too. I have no problems with power after it warms up. I think after I over heated it I might of messed up the spark plugs. Does anyone have any ideas.
