Not running right

Djerv

Hi,

Ive got a new fabric rebuilt engine for my vx220. After 1 mile it started missfiring, I took out the plugs and saw that it was wet in cyl 3. Then I tested the ignition and all the plugs sparking. I tought it maby was the injector leaking, so tried to switch place with one of the others, but still wet in cyl 3. Anyone got an good idea of whats wrong with it? I`ve also tryed another coil just to be sure.

Might be worth checking your compressions, just to make sure your head gaskets ok...also have you changed your plugs around to see if the fault moves?

I was thinking about compression also. Yes, moved the plugs also. Hope there`s nothing wrong with the engine since it just have been running for 1 mile.

also worth checking the wiring loom is ok, you can test this with a meter - just check each injector plug to make sure the voltages are the same :thumbup:

Lets just say i`ve changed the whole engine loom also. Include ecu.
I have same problem no matter what I change on the engine, so start to think there might be engine problem.

Today I`ve checked the compression. Nothing at all on syl 3. Took of the valve cover and found one "roller" lying in the middel. So one of the inlet valves in syl 3 is bendt. Just my type of luck 🙁
