Alright guys I need some help. My truck has a miss on cylinder one. I'm thinking it's the quadzilla module. It's old, before the pulse. Anyone think I could be that?. I know when I first put it on I could put it too the floor for awhile and it would throw the check engine light on and make it miss than it would go away. Now it will be on for a few days than go off and come back on? Any input is appreciated,Thanks guys

 

set quad to PL0 and see if the issue persists...

probably just a sticking injector.
