I'm new to this forum and I just got a 97 bmw 328i last month. I got the check engine light right after I got it and one of the codes was a bad spark plug. I changed it and did a tune up on the car and now I get the p0442 code for a evap system leak and p1421 and p1423 code for the secondary air injection system. when I first start the car up I do smell oil burning and I popped the hood and smoke was coming out from what looked like under the engine, could this be the evap leak?
I don't have a lot of luck with cars, I got this one because a few months ago my transmission went out on my old car, and I don't have the money for something brand new. thank you for reading and if you know anything about this please respond.
