"Cranks, has spark & fuel - either just cranks, or catches but won’t run -
Check Timing, Crank Angle Sensor could be misaligned. Engine could be flooded,
check spark plug for raw fuel.




Runs OK, but no power -
Check timing, set to 15 degrees, 2nd mark from the right on crank pulley.




Drivable but can’t boost above certain psi, or can't give more than 25% throttle without bucking -
Leak in intercooler piping under boost, even a small leak will make the car sputter
and buck with any significant throttle. MAFS or MAFS wiring problem.




Idles OK, but can’t rev past 2500 rpm -
MAFS or MAFS wiring problem."


sounds like you fucked up you MAFS wiring if you've tried different mafs w/ the same outcome.. did you use shielded wire for the sensor or just some regular wire you had layin around?
