[QUOTE="TreeClimber, post: 1301176, member: 16101"] CJs have a fuel return line from the fuel filter. Put it in low range without locking the hubs and drive it. See if it clears up or not. You could have a clogged catalytic convertor. Loosen the exhaust at one of the flanges between the motor and the cat, to allow excess pressure to escape. Yeah, it'll be noisy, but re-drive it, and see if the problems gone. You could have a bad fuel filter, not allowing enough fuel to flow into the car, starving it. You could have a bad fuel line, that's collapsing, and starving the motor, You could have a bad fuel cap, which is not venting properly, thus creating a vacuum in the tank, preventing fuel from pumping properly You could have a weak fuel pump. You could have too much tire for the motor to turn. You could have jumped timing, and the camshaft and crankshaft are no longer in sinc. You can verify by bringing the crank to TDC, and looking at the timing marks of the distributor. I'll think of more could haves.... t [/QUOTE]
