I have a 2007 Explorer with the 4.6 liter. 91,000 miles, I just changed the plugs (that was fun...thank goodness for the Lisle tool!), boots, and fuel filter.
Prior to this, the truck had a miss and would stutter at high speeds. The truck runs awesome now, better then when I bought it 5 years ago.
Yesterday, the check engine light came on. I used my scan tool and it read a P0420 code "Catalyst System Efficiency Below Normal Threshold Bank 1".
I cleared the code and today the light came back on, same code.
Any ideas?
