Hi All,
My car randomly developed what feels like a dead cylinder, it idles rough, its low on power and it generally sounds like one just isn't firing. Wondering if there is anything else I should check to help pinpoint the cause. Here is what I've done so far:
1. Connected noid light to each side of the injector harness, verified each injector is getting a cylinder
2. Used spark plug tester to verify coil is outputting spark at each cylinder - also replaced plugs
3. swapped out for a known good coil/CCCI combo - no change
4. Swapped out chip for a known good one - no change
5. Swapped out computer for a known good one - no change
6. Did a compression test - all cylinders had good compression <140
7. Checked AFR readings - at idle the AFR seems to slowly climb to and lean out to 18+ and fluctuates in this range...not sure what this means, but it should be around 14-15 as that's what I observed prior to this situation occurring.
Anythign else I should be checking to help pinpoint?
