OK, so I proved the theory that we are short on fuel with the carb cleaner trick. I then pulled the injector and hosed the holy hell out of it with carb cleaner and then let it soak in Sea Foam for roughly 24 hours to no avail.
I did look into fuel pressure the poor mans way and can say that it will pump alot of fuel in just the 3 seconds when the key comes on. granted i know that is not what PRESSURE its making just flow. but i did have the tank down and fuel pump out and the pump itself looked new ish and i replaced the pick up screen when i first got the rig.
I have done the pump the throttle test and that definitely seems to help and typically is the only time it can generate much power.
I spent quite a bit of time with a flash light looking in at the injector spray running butterfly with my hand and know that it is shooting a good conical pattern at idle as i can see it hitting the butterfly. but when i open it up its harder to see the pattern and could only see a slight difference in spray when it was bogging vs revving but cant hold it open that long because when rpms do finally rise they obviously rise pretty fast without a load. One thing i did find looks like a homemade wire coming from coil thats spliced in to where injector plugs into connector. I attached a pic of both ends.
I will see if i can find some of that additive and dump some in. I also was told about a trick to try from the guy at the parts store but havent tried it yet, sounded little risky, but to somehow jump the injector with a 9V battery and make it fire hard to see if the plunger is gummed up. Where can I have an injector cleaned professionally? seems like a seal unit.
As far as actually checking fuel pressure i do not have a fuel pressure gauge and when i replaced the fuel filter the fittings were so rusty that 1 broke. so i went too a new inline filter that clamps in.
