So I went to start the truck today, made some funny clunks and shakes and smelled bad. Now it idles high when you start it and then drops way down and stalls out if your idling. Read codes and got: P2195, P2197, and P1233. Any ideas? Input?

 

Well did you check your FPDM? Seems with the code and it running lean, or not getting enough gas, it would throw those O2 codes.

 

Easy place to start is for sure the FPDM. Could easily cause all those symptoms.

 

Already checked and has been replaced. It's a dorman.

 

Unplug it and take it off. Then check to see if the plug has power. If the plug has power, the unit is probably bad.
