Help... odd problem!!
No spark in cyl 5 on #1 engine in twin engine application
moved around spark plugs, coils, wires, and even the ecu to the other engine 1 at a time. NOTHING changes the problem. Motor runs at 4000 rpm and then won't go any further. Runs ok but a little rough from start to 4000 rpm. #5 plug is clean and very wet so we tried with the plug wire off cyl 5 and motor runs exactly the same.
So, the engine must run they way it is without cyl 5.
Could any sensors be causing #5 to not fire? Like O2 or knock sensor??
What do you think is causing this?
tks!!
