Need a little advice please. When I first start up my truck, my CEL comes on. I can drive for a few minutes then the CEL will turn off. Anytime during driving, the CEL will turn on and stay on for awhile then turn off. When it comes on, sometimes the truck will buck a little bit. When the CEL is on, truck performance is slightly slugish. My fuel filter and Air filter are new. The FPR screen is clean. I have pulled both valve covers off and inspected the harnesses and everything looks good. I did find something odd on the harness thats plugs into the IPR. The material used around the wires was a very soft goo, like it got too hot. I was able to clean up the plug and make sure the wires were ok. No change on the CEL. My thoughts are leaning towards the IPR, but this could be an expensive guess. Your help is much appreciated.
