2014 Monsoon 409 Cylinder 1 Misfire MIL - ECM: SPN 65591 FMI 7


Recommended Posts

2014 Axis A24 Monsoon 409

 

Got the following code while surfing, when the MIL Light and Service light started blinking I felt it kinda lose a little power for a second but honestly after that couldn't tell for certain if it was running any different. Drained all the sacs, accelerated a few times, seemed fine but still ended the day.

 

ECM: SPN 65591 FMI 7

 

From what I can tell this is a cylinder 1 misfire? Any tips/ideas on how to determine the root cause? Planning to put in new plugs and test it again.

Also what's the procedure to clear the code? Saw something about 3 heat cycles but want to confirm I do it right.

Check the cap and rotor as well as the plugs.  It might also be a good idea to do a resistance check on your plug wires to see if they need to be changed, or just go ahead and change them.

I have a 2015 VLX 409 that had a slight miss also but no codes showing. I removed all plugs and found #6 plug was a little darker than the rest of the plugs. Went ahead and replaced all plugs and just to be sure I removed the coil from that plug and tried to order from my local dealer without any success. Took the coil to Napa auto and #’s on coil we’re the same as a 2015 Chevy 6 liter truck motor, problem solved without Malibu dealer

Replaced all the plugs, plug from cylinder 1 definitely looked more burnt than the rest (one on the left in the picture below). Resistance checked plug wires and they seemed good. Even tried swapping the coil on #1 and #8 to see if the error moved. No change, still runs perfect. Fully sacked up the boat and surfed with 0 issues or concerns. In the process of trying to do the 3 heat cycles to see if it goes away. (trying to find someone local that can just clear it)

Picture on Spark Plugs

Couple questions.

-On a 2014, will it tell you if a code is inactive or active?

- I noticed on the gauge cluster their are 2 engine lights, one with a picture of an engine that says "Check" , the other says "MIL". The second ones is what I have lit up. From my understanding the MIL light more so pertains to emissions related items? Not necessarily critical damaged/ things that required immediate attention?

Did the problem go away after 3 heat cycles? I’m getting the same codes and want to know if I need to replace plugs, wires, etc. and still have to go to dealer to have them clear it. Also, mine is showing as inactive, does that mean it was possibly just a misfire and may clear up on its own?

It’s coil on plug so you only have to replace spark plugs. It will clear after 3 heat cycles if the problem is fixed.

I see people talking about a cap and rotor. Don’t these engines have coil packs? I just bought a 2014 MXZ with a LS3 Corvette 450. Getting the warning code when I filled all ballast and tried to surf. Boat is running like a top though
