This is not an Axys, but I this area gets much more traffic and I am hoping to get some answers for those smarter than me on the CFI system! This is a 2010 Rush with the 2+2 system.
This is a fresh full rebuild, and I bought it with the PTO rod snapped in half and the case totally ruined.
When cold, the sled will high idle (about 3400 rpm) and run stronger on the PTO side. If I pull the PTO cap, it obviously idles down as it is now running on one. But, when I put the PTO cap back on the cylinder WILL NOT pick back up until I give it some throttle. I have attached a video.
When it's warm, it just runs on the mag side until you give it some gas.
I got it warm and did a couple laps in the yard, at approximately 10% throttle the PTO side kicks in and it runs on both.
My guess is there is an issue with the low speed PTO injector, either the injector itself or electrical.
Here is a list of what I have checked/done:
Injectors were cleaned and flow/ohm tested. I tested the ohms in the harness as well.
TPS was checked
New sock and inline filter, pressure is 60 lbs.
I have swapped plugs.
.020" throttle cable pay and the blades are resting in the stop.
Compression is good at about 130 lbs
Reeds and boot were inspected and were good
It seems all connections are plugged in
With hood on there is no check engine light
It almost seems like and air leak at first, but I am baffled as to why it runs on the PTO side, then won't pick back up. It runs good/normal when it does run on two, but I am not the kind of guy to take of riding when it runs like this.
