SO I have been having engine problems lately, the car is running really rough, and makes some wierd noises right after I turn it on. Acceleration also seems to be decreased. Car has 8000 miles. It jsut started running rough, but it has been doing the start up thing since I got it. I have a CAI, and I was thinking of taking it off and taking the car to the dealer, but I was wondering if it matters if they think you hadone in, or if they know you had one in. Can they deny you service just because of engine mod suspicion. Anyways, someone please answer my questions about the dealer, or give me some advice about what could be wrong with my baby. Thanks in advance.
