I recently took my 3 in for a bad door lock at North penn imports in colmar. The lock was covered under warrenty so they gave my a loaner. Two days later, i get a call and they tell me its done but since my inspection is up this month, should they inspect it. I told them to and call me when its done. Well, they called and tell me that my car doesn't work and that it's stalling. In between all of his jibber jabber, he tells me that they were doing something with the MAF sensor. As soon as he tells me this i start arguing with him. I knew exactly what the dumbass techs did, and anyone who has a CAI installed would also. The retard must have pushed the little retaining clip back into the battery box and pulled my MAF sensor wires. That is a clear no-no when installing a cai as printed in any of the directions. So long story short, they try to blame me and ask me if I would like to fix it. What the hell? I tell them to eat me and that my car better work when i pick it up. It was, but i'm still worried about a possible problem in the future. So watch out, don't let the dealers try to get one over on you. Anyone ever had a similar experience?
