latebird I've been suspecting that possibly the fuel pump is going out all day long. Something to think about while I was mowing all day. I have no idea how to check fuel pressure on this EFI, this is my first one.
bp405 No wash job, I just changed the oil/oil filter, new air filter,new front DD diff fluid,and changed out the AGL trans fluid. One good thing about it breaking down on me it happened with in about 10 foot of my shop door instead of out in the field.
I tried this afternoon to see if any codes would come up, but apparently I'm doing something wrong, because I get nothing coming up. Here's what I do per the owners manual instructions. It says place trans in PARK .Stop the engine (I tried with engine running then turn it off then back on and also just turning the switch to on then off with engine not running to start with).
Turn the key switch to ON position.
Turn the key switch off and on three times in less than five seconds. The word "WAIt" will appear on the screen.
I get no "WAIt" showing on the screen at all, just my regular display of my mileage,clock,or RPM whatever sequence it's in at the time I try. I bet I tried it at least a dozen times with no luck getting into the code sequence section to check for error codes.
Also this afternoon I started up the ATV and increased the throttle just a little bit, it would hold a higher RPM like in the 2400-2500 RPM range and would not come back down to idle when I released the the throttle. I had to slightly fan the throttle to make it come down to regular idle RPM range which on mine is showing 1170-1190 RPM at idle.
