I looked up the codes via the warmer and off buttons on the climate control switch. I had no active codes at the time, but it pulled up 3 previous ones. One of them was for a TPS open switch circuit. I changed it out, and adjusted it. Took care of the hesitation on slight open throttle, but it's still got a fuel knock like the knock sensor is faulty. I'm at a loss right now, and haven't got another way of checking for codes.

 

Well there Wild Bill you had better tell us what car and engine it's on or there just may be a shootout at the OK corral. Maybe this is on your John Deere tractor??

 

Oh, right...........
