SES Code P0102 Help!!!!! Alright, out of the blue my car threw a P0102 MAf low voltage frequency on my 98 SS. I just converted to a TH350 and moser 12 bolt. Of course by throwing this code the car runs like **** and won't even think about idling. Checked the engine sensor fuse and it was blown, replaced it cleared the code with HP tuners and started the car again. Fuse blew again and threw the same code. Checked the O2's, no issues, checked them for melting against the headers and checked the wiring with a relay, all seem to be grounded and functioning properly. Cleaned the MAF out and tried it again and it blew another 20 amp fuse, Unplugged the MAF completely and it blew another fuse and threw the same code. Anyone have any ideas, this is really frustrating!!

That fuse powers the MAF and all 4 O2 sensor heaters. You have to have a short to ground on one of those wires. Since the O2 harnesses run all around the transmission and you just swapped it, you probably have a wire pinched shorting it to ground.
