First off i'd like to say hello, because i havent been on the forum in a while. I have a JDM 1994 MR2 Turbo. 3rd gen 3sgte. not many upgrades just down pipe and boost controller.
Lately my car has been acting weird, I had changed out the cap, rotor, wires, spark plugs, ignitor, coil, and did an oil change and fuel filter change. The car starts fine but when i apply throttle it hesitates and bogs as if its going to stall. It also shoots out black smoke, i guess its running rich?
Any way got it all timed and idles fine, like nothing is wrong, I set it as close to 90degrees btdc. but when i apply throttle it still hesitates, stalls, some times still dies. I did it again and still looking at the timing, and the timing doesn't change when i apply the throttle. So does this mean my ECU has gone bad? I sent out my ecu to get checked, if it is bad, it will cost me $280 to fix, and if its good they will just send it back. any ideas? thanks
