Greetings everyone,
I am kinda new at this forum thing and i just picked up my first bmw saturday night. I am only 16 but i am well educated in the automotive field...dad's a mechanic. Any way i bought a 95' 325i (yes i know my username is misleading) and the CEL is on. The previous owners were complete morons and the car just needs sum TLC!! Today i brought it up to a shop in becker and we did a lot of stuff. Including new plugs, new synthetic oil, brand new tires, new battery, new oil filter, (getting rotors monday) and also gave it an alignment. 1000$ after all that. This is very puzzling to me cuz after all this happened the cars CEL was off and then when i hit about 3000rpm it comes on. Then while im coasting, itll come off...its weird. I as just wondering if you guys could shed some light upon the situtaion. It does have an aftermarket exhaust that just screams so it could be the 02 sensor??
IT would be much appreciated...
