Fault code, Cyl 3 Misfire


Recommended Posts

Hi, I'm a new member.... I just bought a new 08 wakesetter 23 LSV with a Hammerhead 400 hp engine on it. I have a trouble code "Cyl3 Misfire" I have done almost every thing... I changed the CAM and Crank sensors, The distributer cap, the spark plug on this Cyl, the spark plug wire.

please let me know if I'm missing any thing else that I can do.

i would do a compression test and compare all cylinders and if this cylinder is low. do cylinder leak down test. i hope dont have to tell you what to do next.

We just went through the same thing with ours, and it ended up being the ECM. The dealer replaced all the sensors, but nothing changed until he replaced the ECM

Cyl. misfire code means you have something wrong with the ignition system. Not familiar with the new Hammerhead engine, but does that engine have individual coils for each spark plug?

Are you babying the engine? hammerheads do not to be putted around.

Have you made a WOT pass on the engine to burn off the carbon build up in the cylinders?

What octane fuel are you using? How long ago did you fill it up?

Warranty is your friend. Stop pulling out your hair and let the deal take care of this.

I couldn't agree more! WARRANTY!
