12´pro rmk 800 running on one cylinder.

Anyone with an 11/12 should check the plug wires carefully for vibration wear against the head, VES, VES bolts - the way they zip tied and routed them, they can vibrate against the VES fasteners or VES housing, and wear a hole in the wires. Had it happen on my 11, and poo replaced wire/cap/coil under warranty. Those 11's looked like they were wired in a high school shop class.

Seemed like it was changed on the 13/14's, at least both of mine were, and it wasn't a problem anymore. Just another PM item when going through the sled at start, middle, end, of season. Had an injector replaced by poo, too, on the 11 from the wire harness being fastened against the throttle body and wearing down the wire.

Well, i just trusted the dealer

I would have a hard time trusting any dealer that told me minimum stock compression is 159 pounds. My full mod ran that much, but not on 91 pump gas. On average, stock 2-S engines run around 120 static compression.

Edit: a quick google search on the code you posted supports the theory that your issue is TPS related. Your throttle cable isnt sticky, or loose, is it? If not, i would be looking at the TSS system and/or the TPS.

mike the compression spec was probably a misunderstanding between the dealer and the op. I would doubt any one would throw out that number on perpose

Thats the reason i asked if the compression really should be that high.
