Nytro code 37 issues

[Chuck Norris on a sled]

Hi I'm hoping to come accross someone with a lot of experience with Yamaha Nytros or has had the exact same issue as mine and fixed it. Not to be rude but I'm not looking for opinions or theories from people who haven't dealt with the issue.

My 08 Nytro flashes a code 37 and runs very poorly. I replaced the idle control valve (throttle body solenoid) and it ran better for a day until the very end of the day when it started flashing the code again and running at high idle at times and low idle at other times. It even backfired once. When you hammer down on the throttle it it seems to go fine, it just runs poorly otherwise. I've also replaced the spark plugs.

For a while before its started throwing code 37 it seemed to run better when it was cold than when it warmed up.

Any similar occurences? Thank you!

37 code is a bad or dirty #2 injector try running some injector cleaner through it.

Thanks but that's the diagnostic code 37 reference pertaining to the # 2 injector.

It's flashing the fault code 37 which refers to the idle speed control valve.

Then you should be able to put it into Diagnostic mode and look at code #54 to see if your idle control is still the issue.
