Pcm? help!!!! Think my pcm took a dump
Hey guys i have slight problem my car 99 trans am m6 was running fine yesterday then i parked it in the garage and left it there untill i got home from work today. i started it up ran fine then when i got back into the car i noticed that the tach,water temp, and fuel gauge dropped out and the car kind of got a lil miss to it . i could not not connect my computer to it. so i then checked all the fuses, i checked for power and ground to the dlc connector. then i checked continuity from the data wire to the pcm and the wire was ok so im thiniking the pcm? it just happened all of a sudden car ran fine the night before or am i missing something? before i order a new pcm?
thanks,
Scott

also it starts up fin when u rev it up and hold it it starts breaking up . ive checked the grounds i did have an altenator that the regulator was starting to go voltage would drop to 8 then back to 14.8 and the lights woud dim i checked the battery replaced it wioth a known good battery and tried again im getting a new altenator but im thinking the pcm may have went out i dont know what else to check
