bogging & stalling

I have a jeep wrangler 4.0 6cyld straight automatic 1991
The jeep bogs down while iding and sometimes stalls I tried a tune up (wires plugs, oil filter, oil&air filter) the problem persists. I also have a problem when on a highway @ about 55mph I lose power and drop down to 20-30mph I do not know if these are related problem or what ??????

Welcome Dan, I moved your post to the YJ Forum so other Yj owners can have a look at it.

Just getting to work is an adventure.

Run a fuel system cleaner thru as often as you change your oil, I did this with my pathfinder when it was doing the same so it might be related seein as my pathfinder had a TB as well

98% of people when they are about to go into the ditch say "oh shit!" The other 2% are Minnesotans and when we are about to go into a ditch we say "Hold my beer and watch this shit!"
