2012 pro rmk 800 runs on one cylinder

[01reid]

Yeah so sled runs on one cylinder after ten or twenty minutes but would always run back on two when the sled returned to a idle or u pinned it but today it would just always run on one so I changed plugs and it ran fine for a while but then same thing again both plugs look light brown any ideas? Just put new reeds in it and had the tps checked and was good.thanks for any input

Fuel filter?? Take the fuel line off and try to blow through it. Should feel easy to blow through.

whats the compression?

 

[007sevens]

whats the compression?

would low compression hinder its ability to idle.

Did the fuel filter last year to try and fix the problem old one was easy to blow thru and I put a new one on anyhow, compression is 120 with the mtk fix it kit

The check engine comes on every time it rums on one too but goes off as soon as it runs back on two

If the check engine light has come on, that meant it threw a code. I would have the dealer run the codes for you.

 

[01reid]

Sorry forgot to hit reply

 

[007sevens]

you can check the codes yourself but the engine light has to stay on for that.

 

[01reid]

Yeah the dealer said it has to stay on

i misread, had a problem like that with my 12 turned out one cylinder was shot but worked fine with new plugs and a higher rpm.

 

[01reid]

How do u check it yourself? It doesn't flash it just is on

 

[007sevens]

Yeah the dealer said it has to stay on

only for you to read it.

When he hooks the computer to it there will be codes.

Mine was doing the same thing once I don't remember what I did to fix it tho lol. Check the ignition wires I guess il try to remember what I did but I know I changed something or something at the dealer to fix it.

can't remember exactly for the 2012 but it tells you in the owners manual i think

 

[007sevens]

TPS is subject on that machine as well
