Wife called and said wrench icon and it was dead! I went to pick her up and it started and drove home. I replaced the throttle body (didn't clear KAM) and all is well. I've always had the P0420 code since we've bought the truck. I decided to get on the gas on the interstate to see if wrench icon would reappear. It did not, however the check engine light started flashing and it began stuttering and came to a stop just as it did with wrench icon. It did start right back up and drove fine. I checked codes and had several new codes in addition to the P0420 including a throttle body code which I found strange. Maybe it was still in memory?? Any how a tech told me that the cat could be causing all of this trouble. If the exhaust has nowhere to go it backs up causing the misfire codes I had. So I'm researching troubleshooting the cats and got an infrared thermometer but both cats are cooler before the cat and warmer after by about 45-50 degrees, Which indicates they are functioning. The truck has began to rough idle as before I replaced the throttle body but is driving well. I'm currently ordering the OBD to hook to forscan but have no experience using it. I'm stumped. Anyone have experience with this issue?
thanks
