So how do you know if is in time? Wouldn't you atleast be given the timing for idel at an rpm? Could the miss be a bad injector or plug wire? What about a pluged cat? Ive posted before about this problem and the post got off subject and completly out of hand. I guess kids?

What is the BTDC timing degree for a 4.0 LO enging? Anybody know. Want to check timing but the book says it can not be adjusted and doesn't even give you what it should be. I have a miss and debugging step #4 is checking timing for me.

Thanks guys. I will check the timing before I cut any pipes. I'll repost after. :doh:

Ive been replacing lots of stuff. Plusgs, cap, rotor, ICM, KNOCK SENSOR, COOLANT SENSOR (BOTH), CLEANED TB, PUT K&N AIR FILTER, CLEANED INJCTORS. Runs just a little bit smoother since, but same power to wheels problem. I haven't changed oil yet but will soon although I don't know what that will do for power to wheels. It does not consume oil or leak it.

It has an auto with overdrive. Another jeep owner tooker for a spin and said that it shouldn't do what it is doing. It has 30x9.5x15's for tires. How do you check a cat-conv? Do these tranies realy not shift down when put under a load going up hill? That just doesn't make sense.

1987 4.0L 4x4 D44 rear Lacks power. Motor seams to run well. Trainy seams to shift up ok. From dead stop will not break a tire loose. Steep hills the truck will slow down and doesn't seam to shift down like it should. Fluid level good. Does any one have any Ideas?
