Re: 2003 GX345 Misses Under Load
A miss fire can be caused by a lot of things. But I found out that a coolant leak (via head or intake gasket can show up under load to) making a spark plug(s) do strange things. I found that out after towing a 430 back with my 97 Blazer after I purchased it. Watched it on a diagnostic computer (misfire codes popping on the affected cylinders) pulled those plugs and found crystal type build on the plug(s).
So just food for thought. In general on Kawasaki's; Check for correct spark, Pull plugs and check, check plug wires, check coil(s), check trigger(s), Check pickup(s). See engine diagnostics
