What reading is that No, NoX, CO?
With out knowing which reading is way to high, no one can even give a ball park guess as to the problem. Charles
sorry for the omission in past post,but the co level is what is slightly above the required state level...thanks
You need to have the EGR circuit checked. I don't remember if in
1986 the corolla/nova chassis had a vacuum, vacuum & electric, or pure electric driven EGR. Charles This is just a ball park guess.
Why mess with the EGR for a CO failure?
