been fighting this code for a while and doing a lot of research on here too. i want to know if y'all think the problem is in the ecm. the code comes on when the car is cold and still in open loop. no way the car has had time to accurately read the o2. the temp guage will still be at 100 degrees or less. i have already gone through all the usaual suspects and fixed many problems. i am down to the ecm now.
