Ok so I have a #3 cylinder misfire. Which is the third cyl from the front on the passenger side I have found out. To date I have done the following:
Replaced the spark plug. It looked good, only 20k miles on them.
Swapped COP from #2 to #3 no change still stays in #3
Ohmed all bank 1 fuel injectors out last night and all were consistent 16-19 ohms on a warm engine.
Next step is to swap fuel injectors as #3 may be clogged.
Then I guess cyl comp test if that don't work.
Any place I missed so far in my steps?
I have ruled out fuel filter as that should generate random errors as well as MAP and clogged cats. Had pass side exhaust mani replace 1000 miles ago due to warp.
Any advice is welcome
Thank you
Terry
