I just finished upgrading alot on my engine due to a BHG and water pump. I put on a 2.0 mm MHG stopper style from HKS and a brand new To4e 68 trim turbo, a cat back exhaust, test pipe, and a down pipe. its all put together and now its starting up. the problem that i'm haveing is that when the engine warms up and the electric fans come on, the car starts to sputter. like its choking for fuel or air. kinda like a backfire. it only happens when the fans kick on. i decided to take it out for a spin. the car has massive HP but its not using it. it seems very laggy. can anyone tell me why the car is sputtering and why its lagging. PLEASE RESPOND.
I have "Supra Problems!"

its laggy because of your compressor wheel, too big.... the sputtering may be the ECU relearning the car, how many miles since the ECU reset?
prob about 0.2 miles. i was a little afraid to drive so that i wouldnt break something else. i have that kinda luck. I just found out that Coil wasn't sending a spark to the 6th cylinder. i'm gonna replace it. do you think thats all the problem was? Also... it wasn't the turbo lagging, its the engine. i'm guessing that was because of the coil. am I right?
sounds like some of your problem was the coil pack if it was acting up before. try driving "casually" around the neighborhood. my fellow supra driving around the corner from me had almost the same problem.
Did you get the head machined? Lap the block?
Those are necessary.
As far as the way the car's running, TPS out of adjustment? CPS adjusted correctly?

.well, i fixed the coil. still the same shit. i ran the codes and got code 14 and 52. thats the ignition system and the knock sensor, right. i also have a wire connecter thats located next to the intake man. that isnt connected to anything. i cant idenify this connector. it is a black plastic connecter with a black wire and a light green wire. i believe the black wire may have a blue stripe on it. it is coming out of the main harness. it is bundled in with all of the injector wires. WHAT IS THIS CONNECTOR AND WHERE DOES IT CONNECT???? PLEASE HELP.
