Fuel in PTO cylinder

[jsledder]

Last trip out I started having troubles with the low end performance/reverse on my 9. Looking through all the search results and it looks like an electrical issue, I set the TPS as per MH's video (it was a little off), tested the harness for continuity, and pulled the reeds just to check them. When I pulled the reeds I found excess fuel sitting in the cage and a small amount poured out when I pulled the reeds from the intake. I had a single blink of the check engine light when running at low speeds, it would clean up and run good up to about 7800r's and then drop to 7500, anything under 4500 it would almost die and at idle it wouldn't idle high enough to keep the MFD powered up.

Any way to test the injector or is it a replace and try type fix? I visually checked the harness going to the injector and it was free of any pinches and not rubbing on anything.

Leaving town today and wont be back until late Wednesday and have a trip coming up Friday. Right now my plan it to put the newly set throttle body back in, change the fuel filter and dump some fuel injector cleaner in the tank and see if I can get lucky, unless any of you experts have some more advise.

I've been pretty lucky as far as I'm concerned with this thing, bought it with less than 500 miles on it and addressed pretty much everything that needed to be addressed, and now I'm getting up to about 1500 miles and really haven't had a problem other than some self-inflicted injuries and motor mounts. So I suppose all the electrical gremlins are going to start causing some major headaches.

almost sounds like you are only running on one cylinder...try pulling one plug cap off, put it back on then pull the other off and put it back on when it is running to see if you notice a difference.

If you think an injector is bad, you can swap it to the other side and see if your symptoms follow.

I've experienced four issues that have given me poor idle problems:
1. coil had a pushed pin in the connector where it plugs into the harness
2. bad TPS pigtail
3. inner sheath on the flywheel cutting into the stator wires
4. injector wire was chaffed and cut inside the boot at the injector

Can't test injectors. Indydan and witchhunter.com is your only option to have them rebuilt and basically new after that and worth the money..do all injectors at once.
