so had some problems. So far had a misfire cy 1 leaking injector which lead to light scoring replaced those spark plugs and checked the coils. No check engine light anymore but I have a stutter feel when I’m idiling and cold starting is kind of rough.
Computer is saying my cng rail is at -84 does anyone have experience with this
