It idles fine but when i swapped it in my car it sputters and backfires when i give it gas. When i floor it wont go past 2K. The timing is at 14 tdc. every plug is connected, its not giving me a CEL. stock everything. im also using the ecu he had in his car. Any help will be appreciated. I need to smog my car ASAP.

ok what ECU is in the car. what was he using for ECU?. make sure the ECU is tuned for the motor if it's chipped. swap it out with a factory one see if it fixes.
seems like that's the last thing..
and yes if the wires were not put into that plug correctly. the one u said u accidently pulled off. it will mess with the car. ur pretty much reversing the wiring.
