2.5l stalling and bogging with backfire
I have a 97 tj with a 2.5 manual trans. The jeep started bogging out on me after driving a short distance. When it does if you let it idle it will run but if you try to give it gas it Boggs out and if you persist it will backfire in the exaust. If you turn it off it will restart but do the same thing but the occurrence. Will be sooner than before. What I have done since this started is. Now crank position sensor, new cam position sensor, new plugs, wires, cap and rotor. New fuel pump (shop diagnosis of problem never made it home) pulled the head new valve job, new exaust manifold. Cleaned the intake by spraying, haven't pulled all the sensors yet. Unplugged the front o2 sensor with no change. When I put it back together from the head rework, it acted like it was fixed but the other night when it was cold I started it up and it did it within a few feet of the drive. I limped around the block and it straightened up by the time I got around the block.
I love this crap!!
