Its a 93 yj w/ 58000 miles. I have replaced Tranny at 50000. I replaced a week ago coil-plugs-cap-rotor-wires.

It runs perfect for the first 5-10 minutes. After It "bogs" around 2000 RPMs in every gear. Shut it off for about 5-10 minutes and it runs great again for a few miles and then starts same thing. If you press in the clutch it revs all the way. When in gear, you can hold it to the floor and feels like a tractor pull. Never happens at first start up. If driven for 15-20 miles it seems to get worse.

Also had timing reset about a week ago. Just started this week--it stumbles a bit while idling--intermittently. May drop to 3-400 rpm and then back up around 900. Never cuts off.

PLEASE HELP!!! REWARD
