Ok so after many months I got my pig running. I still have a few issues with it. Some minor but one is not. I swapped in a 360 and have a mopar pcm hooked up. I removed the egr and evap. All the sensors on the motor are new. When I initially start the truck from cold it runs perfect no check engine light at all. After it runs for about 5min or so the check engine light comes on, it spark knocks, and loses power. It does this with the original pcm and the mopar pcm. Does anyone have a clue as to a possible cause? I read somewhere that some have put a 1/4watt resistor across the evap connector but I have not and I cannot find the original post either. Could that be the cause? The only engine codes I throw are evap and egr. Any and all help would be appreciated.
