Well I just got back from the dealer. It was the maf and throttle body. I have no idea what would cause this but was told it would be around 1500.00 without the warranty. Thank god I got the extended one!! If anyone else has had the same problem please let me know about your experience. Mine was good due to the dealer(A.W. Golden) in south east Pa. The funny thing is that my VX ran fine even though these are crucial parts.
