I am having power loss up hills or/and under load at 3K RPM. When Im climbing the whole trooper will jerk slightly, the rpms seem constant and all but if I give it more gas it will completly stumble. This is a new rebuilt motor with a recently failed headgasket, head gasket was replaced. I do notice a bit of tranny fluid coming from manual transmission, could the tanny be slipping? I know it isnt the clutch, rear axle or drive shaft(s).
The morons at jiffy lube put atf in the tranny when it was there instead of reg. oil. as it calls for in my original owners manual. They showed me their specs on the atf and say Isuzu calls for atf instead of oil now??? WTF??
So I rand with the ATF, now problems are croping up? Could this be engine related spudering at high end rpms related to fuel spark issue? I replaced fuel filter & dumped some fuel injector cleaner in the tank thinking the fuel delivery could be the problem with no change. I havent looked at the plugs, wires and cap rotor yet. Could it be distributor time? I can rev the thing to 3 gran with no spudder when it isnt under load though. Any suggestions would be helpfull... especialy if you have experienced this with your 2.6l Isuzu
THANKS
