Great information 2 be honest mine has a very small miss fire so I'm pretty sure it has a coil going winter is tuff here in Minnesota so I dont mind giving it a full blown tune up regardless plugs 02 sensors air filter pcv. Valve cover gaskets as well .
Any recommendations on the Bosch vs Goodwin's on the 02s?

Fingers/toes are crossed!
The lights are off!!! Two days ago after I filled up, 91 octane always, I added a bottle of Techron complete fuel system cleaner (it was BOGO at Auto Zone!) and proceeded with the 55 mile drive UPHILL to my home. My VSC and check engine lights are off!! Could they repeatedly be coming back on from running the fueltank low and sucking gunk into the fuel system?!? I hope that's it! I have to stop that!!! Maybe an oil/fuel filter change is in order!
Thanks to all who have contributed to the solution. I'll keep you posted!!!
