Just spent from the end of May to yesterday trying to figure out why my AEM wideband wasn't showing the proper voltage on Link. It was a bad wideband and ended up trashing it and getting an Innovate DB gauge. Finally got it up and running yesterday, idling real good, then I shut it off. Come back to fire it up and do more tuning and it's only running on cylinders 3 and 4. Well, after disabling injectors 1 & 2 and no change, then both 3 &4, both of those made a difference in how the car ran.
I really don't wanna spend forever on THIS problem too just to try and diagnose the issue. Wanna make this quick cause I wanna be driving my car again next week. So I'm wondering what all could cause the problems, and how to test each item to narrow it down. Please dumb it down some for the electrically stupid.
Items I know of so far would be coil pack, power transistor, cas (maybe?) and cps (maybe, again?), bad wiring, and ecu. Thanks for any input into this.
