2004 PCM ZR6 Rough Running

[tpayner19]

My 2004 Super Sport Nautique w/ PCM ZR6 starts and idles fine. Gets up in plow then starts reducing speed and running rough. I know there is a Reduced Throttle/Limp mode and my oil is fine and temp is perfect and maintained. Full service performed end of season last year and has been running fine until this week. My tachometer is showing 3000 at idle but is is not revving at 3000. Does anyone have a thought or do I just bite it and go to dealer? I think that is it but if anyone has ideas please let me know. Thanks i. Advance.

Start with simple checks....plugs, wires, clean fuel?

Mine was the same way and a change in plugs and wires did the trick. I hear it over and over...new plugs (the proper plugs) every 200 hours and I believe it.

Exactly....New plugs and wires did the trick for my 06. Wires were worst culprit.
