Answer
David:Are you sure you got all the marks right? Sometimes it takes me, well up to three times to get those marks. But then your car is not that old, I would find out what those codes are and get those sensors replaced. They might be your problem. I wish I could help with that, but I mostly work on cars 1996 and back. So my code book does not have your year of car in it. But surely you have a repair manual for your car? Or else got an AutoZone close by? They could help you with those codes too. I think it could be those sensors that are out, as the computer has to read all the sensors through out the engine to set up how that car will run. If one or two sensors are out, it messes up the whole thing. I hope this helps and good luck! Linda
