Hello all

at times my tc light will stay on after I start the car other times it just decides to come on while driving. when this happens the car runs very rich/rough! black soot at the tail pipe and all! sometimes stalls at lights etc etc... also the temp gauge has a mind of its own at these times bouncing from 40 to 90 or anything in between/over. when the tc light is out the car works just fine.... so my question I guess is what condition from a cold start can cause the tc light to stay on?
only other prob with the car is the drl 's don't work either... put the car in drive drivers side headlight flashes 5 times then nothing out and stay out... would the tc and the drl both be controlled by the bcm ?
 
have you had the ecm and bcm scanned for codes in memory? Try checking the BCM connector for a loose or corroded connection.
 
no codes (last ones were for ox sens replaced) I have a spare bcm module just wasn't sure if I should try it or would it compound my problem
 
thats the ecm, did you have the BCM checked for codes? A different BCM may cause issues due to the VIN being in the BCM memory.
