Can anyone help troubleshoot a reoccurring issue I have been having with my 2012 RXT 260....
I am the original owner so I am aware of the history and have always properly maintained/flushed the pwc after use etc. The pwc now has 167 hours after 2.5 years of use. I have always used 90 octane pure gas.
The problem is that the boat seems to require a new set of spark plugs every week of riding or else the check engine light comes on and stalls. The plugs I use are the ones recommended by Sea Doo.
For example, four weeks ago I changed the oil, plugs, and fuel. The machine ran beautifully all day of all types of riding in the gulf. Took it home flushed and engine, washed down the engine, and sprayed it down with sea doo recommended lube. Took it to the lake the next day and again it ran like a charm...70 mph great acceleration and power etc. no problems.
Six days later take it to the gulf.... Starts fine, the check engine light comes on and it only will idle...sometimes I can restart the machine, and let it idle and very very slowly and slowly add throttle until it warms up. If I do this for 15 minutes of riding, eventually it seems the machine warms up and seems to run fine... otherwise, I am forced to change the spark plugs in order to get the check engine light to go of and get the boat running perfectly again.
Yesterday, one week after again changing the plugs (and having the machine run perfectly), the check engine light came on again. I could be babied up to 50 mph and 6k rmp, but if I punched it or went over 6k the machine stalled and the check engine light would come on.
In any case this has been happening with more frequency over the past 50 hours when I last had the machine serviced for this problem. The certified shop had connected the machine to BUDS computer and said nothing was wrong. They changed the plugs and the gas (saying it was probably bad fuel) and charged me $400 for doing what I already had done myself. Could this be a computer or some sort of sensor problem? The pwc is under warranty, but if the dealer cant find the root issue, changes the plugs, and says its probably bad gas, then I get charged for maintenance and service check etc. without solving the root issue.
I have since used two different stations 90 octane ethanol free gas and some recommended fuel additive k-100, but still get this check engine light and stall issues start up again after just two or three times of taking the pwc out requiring another spark plug change. If had to change the spark plugs about every 30 hours of riding after this problem first started at 100 hours , but now its happening about every 5-10 hours of riding.
Thanks for any insights you might have.
