Redfox340 Posted December 8, 2003 Report Posted December 8, 2003 Since you have a OBDI system, ground the system to read to the trouble codes. From there, you can narrow down to what circuit(s) are fouling out on you. Check W-Body Performance - ECM Diagnosis (OBDI) for the procedure and W-Body.com for codes explainations. - Erik Quote
Slade901 Posted December 8, 2003 Report Posted December 8, 2003 Check the TDC like what Redfox340 said and that should give you an idea what is failing. I hope you don't have the dreaded 42 code. Quote
AWeb80 Posted December 8, 2003 Report Posted December 8, 2003 I hope you don't have the dreaded 42 code. Why is it dreaded? Quote
Slade901 Posted December 8, 2003 Report Posted December 8, 2003 It involves testing multiple components, Crankshaft Position Sensor, Camshaft Position Sensor (if applicable), knock sensor, Ignition Control Module, Ignition Coils, ECM, ECM Eprom. 90KUTTY what TDC (Trouble Diagnostics Code) did you get?

90KUTTY Posted December 8, 2003 Author Report Posted December 8, 2003 code 44 i guess my o2 sensor cracked or somethen so i went and and got one at the junk yard Quote
supreme_style21 Posted December 8, 2003 Report Posted December 8, 2003 Wouldn't it be cheaper in the long run to go buy a new one? Who knows what kind of shape those sensors are in when you get 'em from a yard. Quote
90KUTTY Posted December 8, 2003 Author Report Posted December 8, 2003 i guess but i got it 4 free it will last till some cash comes in Quote
Redfox340 Posted December 8, 2003 Report Posted December 8, 2003 i guess but i got it 4 free it will last till some cash comes in Put the free replacement in, pull the battery or ECM fuse for 15 minuts, and restart car. If the SES light doesn't return, you found the culprit! If not, some more diagnosis is in order. - Erik Quote
