Jetski Sputters and Low RPM?

2002 Honda ARX1200 Aquatrax Jet Ski Sputters and Gives Low RPM

It Starts and runs fine,but in minutes it will sputter and needs to be stopped.

WHAT IS THE CAUSE OF THIS PROBLEM?

One common problem noticed on this model Honda jet-ski is dirty connectors.
In the front of the engine under where the seat clips you will find 2 large multi wire plugs, inspect both of these plugs for corrosion and make sure when the connectors are plugged in that the wires do in fact insert into the other connector and are not pushed out the back of the plug. Those connectors are a common problem with that ski.In most of such cases the connectors are the issue.Disconnecting the wires from this connectors,cleaning the wire terminals and connectors with proper contact cleaner,then reinserting the wires properly to there respective connectors helps/

IF THAT IS NOT THE CASE THEN?

Then in most of such cases you get FI/light buzzer warning indication.
This indicates that there error codes stored in the system.
You will have to retrieve the error codes.Those error codes will tell you whats the issue is.

To retrieve error codes manually try this simple procedure ,jump the service check connector to get the stored codes.

This details will help.
Thanks.

1995 Toyota LS: Misfire at idle or low RPM

The intermittent misfire problem.
The cylinder 2 misfires sometimes but not regularly.

First the basics needs to be checked inspected.
the Spark plug wires,ignition coils,distributor cap,rotors, all needs to be checked.In most cases this parts are weak or faulty causing the problem.
But if all this parts are already checked ok or replaced.THEN,
The intermittent misfire would probably rule out compression unless there was an issue with a valve sticking but this is usually associated with some ticking noise. If the problem is intermittent it may be a problem with the injector. You can try and swap number 2 with one of the other cylinders to see if the problem transfers to that cylinder. It sounds like you have ruled out the ignition things which only leaves injectors or compression.

But if all injectors are also checked OK then,in some cases the problem was crank sensor.
A crank sensor normally will not cause this without setting a code. But if there is no Code set in vehicles computer then, Have you checked for any intake leaks? If not then please check.This is about the only thing that would cause a misfire at idle or low RPM but not be noticed on harder acceleration.

This details will help.
Thanks.
