check your diffs could have gotten sand or mud creating more friction just an idea!

so it defenetly not the exaust because i just got donw making a new one what sits nice and has a good amount of play plus looks nice and clean

but i did find that my front drive shaft was blown so i took that out and took her for a spin hoping that that what was causing all my problems

but no it dose vibrate a lot less but im still having problems

the jeep still feels under powered and shifts late

when in 3rd it makes a high pitched humming tone almost winding sounding

when in 4th and going up a hill it wont shift down till the rpms drop downs to 1500


any one got any ideas

im going to my friends shop in a few days to get it hooked up to a comp and see if we can find anything wrong that way

and i just servixed the diffs the rear had a tiny bit of water in it but i sprayed it with a **** ton of break cleaner to get it super clean

Take a look at your flexplate, it could be cracked or loose, and that could cause problems for your crank position sensor in picking up signal to fire the coils and injectors.

dame i just watched a video of a bad flex plate and it was crazy but i think thats what it might be just not as bad
