Okay so 04 gp gt2 165k miles mods 190 t stat and cold air intake. I have a chugging issue when its under load and at operating temp on cruise it goes away with light throttle also wot at operating temp stops when I get out of throttle same feeling chug kind of feels like a misfire but not as aggressive. No codes and I've replaced the plugs wires checked plugs not cracked (used mirror and light so no chance they broke after checking) new wires had coils checked there good cleaned posts on coils and new electro grease new fuel filter use sea foam regularly gas and vacuum. I'm going to be doing all new gaskets entire top motor in the spring theres no fuel pooling around injectors no rotten egg smell like sulfur tonight I will try get a vid and push it see if cat will glow red? HELP!!!!!!!!!!!
