I had just replaced the head gasket on my 94 325i an. It has been running at 1500 RPM in park and fine whille driving. Now it is running at 500 RPM when ever im not on the gas at all. I don't know why. So please if you know, Please let me know. Also I am having a problem with my hazard lights, They just turn on when ever they want to. I have no idea why. The car has been hit in the front but I drove it for six months or so just fine. It just started very randomly.
