When I start my car the engine seems to get around 1000 rpm but then randomly in park starts to go down to 0 and then all the way up to 7000. I don't know what it is, but I have change my tail lights to an after market product and it shows a caution light. I'm just wondering if anyone can give me some guidance!! Thanks fellow Bimmer bros!!
