I still have the problem with the light coming back on after I erase the codes...and the same codes keep coming up. I did get my car to pas emissions last week by erasing the code to clear the light but it had taken a lot more drive cycles before it came back on. So far I have replaced the PCV Valve, Gas Cap. My next step to replace the plugs. which I had learned from the link you sent me. Can anyone explain what a pending code is? the DTCs are P410 and P410 PD.
I will still continue to solve the situation.
