    Had this same problem mine was the timing belt it was off by two teeth. You may wanna check that. Is you CEL flashing or solid? Could also be fuel pump, fuel injectors or spark plugs could be as simple as just needing to clean the MAF. There are to many scenarios it could be. Just have to check them off the list one by one. That's what I did:P
