I'm driving a 1997 Tj. 4.0. Every time I start it after not being started for awhile, I wait about a minute, then it starts to bog down like it's about to die. So I turn off the key, and restart it a few seconds later. Then it's fine. I always let it idle for several minutes before driving. Then sometimes after all of that, I drive about 100 feet and it starts to cut out again. I then restart it, then it's totally fine. Any help solving this would be greatly appreciated.
