I think my computer is fried help!!!
Hay guys, I have a 95 gt 5.0 and it won't idle at all. If you hold the gas down it'll run fine for a while, about 1 minute or so then the check engine light goes out. And as soon as that happens it starts missing really bad and blowing black smoke out the pipes. If you keep it running it will eventually straiten up and run smooth again, But still won't idle. I tried to pull codes and it won't work it clicks one sensor and then dose nothing. I had the ignition module checked and it was good. I changed the tps,cleaned the maf sensor and checked all the connections. The check engine light going out and missing has me thinking there is something wrong with the computer. But if I unhook the maf sensor it doesn't do it. It just hesitates when you vary first touch the throttle because of it being unhooked. I'm stumped!!!!! Any help will be awesome thanks.

Ok guys, I used joel5.0's method to pull codes and I got from self test 159 MAF sensor fault above or below voltage. And from stored codes 157 MAF sensor fault low voltage, 158 MAF sensor fault high voltage, 332 insufficient EGR flow detected. So my question is should I replace these or is there something else that causes them to do this? Again thanks.

check for bad grounds, there may be one near the battory that goes from battory to chassis wall then plugs into cable, sometimes there is a connector there that gets eaten with acid, and you get erratic ground, erratic performance
