Rear End ??

I Have a '93 YJ I Replaced the spark plugs wires cap and roter. then few days later i was driving down the freeway and it slowed down and wouldn't go anyfaster or maintain speed i could feel something hitting the floorboard assuming it was the exhaust pipe and was kinda felt like it was missing but couldn't hear any backfiring or anything It will idle find and runs fine most of the time when i restart it and take off it usually solves the problem for a few minutes . . . we noticed that it has been kinda jerking when taking off and when this happens it kinda pulls toward the passanger side we pulled the housing off the rearend and checked the cap and rotor but nothing seems out of place . . . it usually only does it at freeway speed i'm assuming it has to to with something heating up but no fluid seems low . . . long story short at first i assumed it had something to do with the stuff i replaced but may be the rear end it causing the tranny to jerk alittle making me feel something in the floorboard Anyone ever had anything like this happen before ??

Not sure about the pulling part but it almost sounds like a clogged exhaust.

I think rear end failures are usually a lot more dramatic, and usually leave little doubt as to where the problem is.

I think I would be looking at the front end parts....

Pulling to the side when it slows down is 'really' bad news! That means something is stressing the shit out of either a front end part that is about to fail or a bushing that already has failed.

The exhaust banging the floor when the engine loads up like that and the jerky starts likely means you have a broken engine mount or broken tranny mount as well. I would be looking at the driver's side mount. This would just be a symptom of the load, not the cause.

Do you have any issues or noises when turning? Sometimes the front axle u-joints seize up, but you usually notice that as heavy steering.

When looking at the front wheels, do they look straight up and down or is one tilted in at the top?

You can check out your cat for blockage by checking the manifold vacuum. If it is really low, suspect a blocked up cat.
