Bad Mass Air??
Help! I just installed a 393 in my 93 5.0, it has an ATI D1 Procharger, with 50 lb injectors. The car idles fine, but when I try to drive it, it will buck and sometimes almost stall, also the check engine light comes on, the codes shows a bad mass air. I have a bullet 75mm, that I just sent back to be recalibrated, so could it be that it wasn't calibrated right or that it is bad all together? The fuel pressure is set right and the TPS is set. The only code that shows up is the mass air code. Anybody have some suggestions?????? Thanks

I forget which code# it is, but it says mass air fault, check ground. Something like that.

Have you checked to make sure that the ground on the sensor has continuity with the chasis ground? Perhaps you have a short in your sensor harness ground wire?
