700 miles odb11 egr, cat,oxygen still not ready
My ten day extension on inspection is done n im bumming. 1996 gmc jimmy runs flawless all i did was install new battery a week before inspection. I been searching n found one guy who replaced thermostat n it made the cat ready. I have 3 or the 6 ready so if i can get one more i can get inspection. I also see another member saying a bad 02 senser can cause things to be not ready on odb11. My question on that is how the heck can i tell which o2 is bad. No check engine light n truck runs real good
