It might be fouled plugs...check and replace them if needed.
Spark Plugs for 02 GTX DI. NGK ZFR4F-11 Gap/ 1.1mm or .04 in.
This should solve your problem. Keep us posted.

I had a bad injector on my 2001 GTX DI last year. The symptoms were just that the engine ran rough, uneven and vibrated more than usual. I replaced the fuel filter, but that did not help. Ultimately had the jetski diagnosed by a dealer. I installed the injectors myself and all is well. But your problem may be somewhere else....

i checked the plugs and they are completely spotless, like the engine is running flawlessly, yet it went from topping out at 65-70 mph to 60-65 mph.
