I had 4000 miles on a new set of Autolite Platinum spark plugs before I had this problem with it not wanting to start. Well, I bought a new set of standard Autolite plugs. I started to replace each one. I pulled one out and checked the spark while my wife cranked it over. It had a good blue /white spark, plug looked clean and compression was good. I then replaced it with a new one. After changing 2 plugs and while testing the 3rd plug the engine started up. After installing all the new plugs the engine runs good and is back to the same power it had before having this problem with the new Autolite Platinum plugs.
Has anyone ever been through this with a new set of Autolite Platinum plugs? I will be letting Autolite know about this problem.
Now I am getting error codes 16, 41, 12, 77 and my check engine light comes on after driving a couple miles. It resets after I shut the engine off and then comes on again after a couple miles. I then changed the HO2S sensor and the fuel pressure regulator. Still the same error codes come back and the check engine light comes on. I performed a Wiggle test and it was OK. I am back to square one. Confused!
