Worked fine. I swapped out the battery and then #2 is misfiring. Noticeable miss when driving under load.
1. Swapped plug 2 and 4. No change. Still misfiring on #2
2. Swapped coil packs. No change. Still misfiring on #2
3. Swapped in a new injector in #2. No change. Still misfiring on #2
Getting spark at #2 plug
Continuity between #2 injector wire and injector plug and ECM
No idea what to try from here other than compression and leakdown tests. I just can't see that going to shit from a battery swap but I can't see anything really going to shit from a battery swap. Has to be a coincidence.
Any ideas from those smarter than me?
