Baller Stevie Boy Posted June 21, 2017 Baller Share Posted June 21, 2017 Check out the sensor on the front bottom pulley. Link to comment Share on other sites More sharing options...
Baller JAG Posted June 21, 2017 Baller Share Posted June 21, 2017 Always go back to the last thing you did. Can you add enough "new" gas? On my similar era PCM, rough running always had me looking at a very dirty rotor and distributor cap. But, if the problem started after adding fuel, then try and refill with fresh gas.

Baller MNshortliner Posted June 21, 2017 Baller Share Posted June 21, 2017 If you change the filters put the gas from them in a clear container and look for water in the fuel Link to comment Share on other sites More sharing options...
Baller 6balls Posted June 21, 2017 Baller Share Posted June 21, 2017 check engine light on? Link to comment Share on other sites More sharing options...
Baller bananaron Posted June 21, 2017 Author Baller Share Posted June 21, 2017 ck engine light is not on.Is the fuel filter inside the fuel control cell? And where is the second filter located? Link to comment Share on other sites More sharing options...
Baller JAG Posted June 21, 2017 Baller Share Posted June 21, 2017 I believe it's a 5.8L PCM? If so, follow the fuel feed line going into the FCC. That will be the outlet of the low pressure pump which has an internal screen. Disassembly of the pump is required to get to the screen. (the low pressure pump pulls fuel from the tank for delivery to the higher pressure FCC) Link to comment Share on other sites More sharing options...
Baller Edmund Posted June 21, 2017 Baller Share Posted June 21, 2017 Could be that the low pressure fuel pump needs replacing which is very common on the GT-40 engine. Mine went out last fall on my 1998. If that is your problem, then typically the engine will run great until it hits the operating temperature of 160 degrees, and then will either drop to a rough idle or completely cut out. It's an easy fix to replace. Link to comment Share on other sites More sharing options...
Baller eleeski Posted June 21, 2017 Baller Share Posted June 21, 2017 Guaranteed fix: Remove rope from pylon. Replace from pylon down with new 200, MC Prostar, Malibu or Carbon Pro. Reattach rope to pylon. Ski. Link to comment Share on other sites More sharing options...

Baller bananaron Posted June 23, 2017 Author Baller Share Posted June 23, 2017 Thanks for all of the helpful ideas.I think it was some bad gas at the bottom of the tank.Ran some seafoam and fresh gas and now its running normal.@eleeski I agree this is not my boat however a new one would be great.I am still looking for a boat to purchase.

Baller_ MISkier Posted June 23, 2017 Baller_ Share Posted June 23, 2017 @eleeski, didn't you forget the step where they send you the old boat/engine/ski or whatever is now "shot"? The worst slalom equipment I own is between my ears. Link to comment Share on other sites More sharing options...
