Hope someone can help, can not get wot, customer replaced #2 and #4coils and wires. He had to a dealership six times and could not find a thing wrong, [intermit] problem, no codes. I got the engine, did leak down all good, fuel and air is good. Drained line on air gauge and seen water coming out, resealed head on compressor, cleaned port rail and injectors [air and fuel]. New plugs, tested all injectors, crank sensor, tps sensor. At ideal cyld misfire is good. Took to water powered up on trailer at wot did miss fire test #2 and #4 no difference. Shut down pulled wires on 2 and 4 spark plugs and no difference. Pulled plugs and plugs were washed clean. Pulled air plentum to check reeds and all are good. Any ideas? Thank You, Rick.

Is the jet impeller in good shape?

Impeller is new, engine has no overheat problems.

I guess I would take a good look at the stator, If you have it narrowed down to 2 & 4. Also I would check the fuel injector wiring.

This is a opti, no stator, the harness is good. Moved #2 # 4 air injectors and coils still not burning on #2 and #4? both have good spark at wot. Too much fuel. plugs are washed clean. ECM maybe? Fuel injectors maybe? Thank's buddy.
