3rd cyl. misfire problem?

I'm working on an 01 mitsu. galant 2.4L and it's been misfiring on #3.

The CKP sensor, plugs, wires, and coils are unsullied.
I've swapped coils, spark plugs and injectors between cylinders without a revision in symptoms.
The injectors hold signal and the plugs are firing.
Compression test come up well in specs also.

I was contained by the shop today to attempt to get this entry figured out but I'm freshly plain out of ideas at this point. I would greatly appreciate any guidance willing to be given. Thanks...

Ignition system?

Can anybody report to me how to...


do a "slick down" test on that cylinder - it's almost the only diagnostic tool you've get left to try. A bleed down test will assist you figure out what's going on, such as fruitless valves, rings, etc.
