Please and thank you! Is the code gone? Can't help much with out more info! You may have a bad injector ! try crackin injection lines one at a time see which one does not effect the engine rpms! post all of your symptoms is the engine smoking if so what colour is the smoke!?

Joey Mack Posted October 3, 2022 Share Posted October 3, 2022 cracked wire for the EUP?? The last one I built also had worn EUP lobes,, litteraly worn the lifts right off the lobes.. Did you pull the EUP roller and inspect it and the cam lobe? 2 Quote Link to comment Share on other sites More sharing options...
