Car: CAMORRA 1987 Engine: 383 HSR Megasquirted Transmission: T-65 Axle/Gears: GM 3.43 -4th gen F-body | MAF problem (code 33 and 34)
not sure if proper board so if not please move to one.
i have two fbodies, one is stock '87 305 with #22 injectors (ECM stock)
second one is 383 with #32 injectors but still stock ECM ('88 350 engine).
Both had problem with MAF codes so i bought one another and pluged to 305 and got code 33, i have swiched ECM with one from 350 and got same error code of 33.
Then i went to my 383 and pluged same MAF and 305 ECM, car was verry weak, idlling at 500RPM and if you would try to touch gas pedal engine just kilsl but no error code at all, engine runs very rich. same MAF, same 383 but 350 ECM and car gets code 34  but runs like hell!
any suggestions what that might be, today i will be trying with 4th MAF but maybe ant hint why this happened, is it MAF broken or wiring issue ??
