Ok…. A couple weeks ago my car (95 318is) would start then immediately shut off... the check engine light can on... blah blah... So I had it towed to a mechanic (they work on imports) so they ended up cleaning the MAF sensor (because the diagnostics test showed that something was wrong with the MAF sensor.. and if it continued I would need to get a new one) and I got a tune up… so then a few days later the car started doing the same thing, took it back to the mechanic and got a new MAF sensor… today I go to start up my car.. And to my surprise it’s doing the same thing!! Do you guys have any clue what could be wrong with it??
