diagnostic help well, my tpi conversion is nearly done on my 82 trans am, so far have added it, edelbrock tes headers eliminated the muffler with 2 1/2 inch tailpipes only, which by the way the car sounds absolutely awsome for a stock LG-4, however I'm having a problem my check engine light is now on constantly, but first let me say wiring is not the problem since it is a complete harness out of a running 87 trans am, and the fuel pump is new, let me describe symtoms that car is encountering, 1 idles at around 800rpm (nuetral) after warm 2 whenever I open the throttle fast it wants to die 3 fires first turn of the key cold or hot 4 how do I flash the check engine light, please tell me eactely what wires to jump (from top to bottom right to left ect.) 4 is there a link here that give ecm codes. got a bad felling Im going to see a code for the mass airflow sensor :o( ............ kaaaaaaching $$$$$$$$$ will post some pictures of it when its all finished |
....check the tech section on the front page, it has all the codes listed there as well as what terminals to jump(A&B). Keep reading the whole tech section, not just on code extraction part, it will help you out quite a bit. |
ok I'm getting a code 33, which Ive been reading about for the last hour so that one is not a problem, however I'm also getting code 36 ...... one other thing I failed to mention, I know I have a burned out fusible link at the starter since I have no battery power at the fusebox, could this be causing my trouble by chance ? |
ok so maybe code 33 is a bigger problem than I thought, upon closer looking I found the relay wires were sort of bare, so I replaced the relays and plug ends with weatherpack relays, however still no power to my blue wire at the maf, red wire gets power though while jumping PIN G on the alcl, no something interesting the red & the blue wires were spliced at sometime right at the mass airflow sensors plug, does this blue wire originate from the ECM itself ? or from the burn off relay, I switched ECM's by the way, that didn't do any better at all, so what do you all think the wire is shorted out somewhere going to the ECM its self ? oh and yes the relays are getting power and all |
new update code 33 goes away if I cover my air filter up with a towel, I also need to add that I made my own intake air track and stuck a air cleaner on the end of the mass airflow sensor, with this what do you guys think bad mass airflow sensor ? |
