| The 91 TT z is pulling a code 12. unplugging and plugging back in maf will not help, idles ok until it gets out of warm-up cycle then jumpy but stays running. TPS has been adjusted, adjusting it either way when running does not truly affect idle but I do hear a click from it, it tests ok on mulitmeter Maf harness has power going to it to signal wire and ground is there. I've tried 2 mafs, harness is 1.5 years old, tt ecu Carbon canister delete has been performed. I have a 3rd maf on the way but not sure if that will fix. Could it be a bad boost leak? Pretty sure I hooked these guys up nice and tight when I check I dont see any apparent leaks. Wont rev past 2500rpm
