hello, i have a 1989 jeep cherokee, with a couple issues. i have had it for about 2 years and i have experienced engine hesitation and lagging on start up. hesitation sometimes occurs while driving. i would drive for awhile and my engine would start hesitating without a known cause. i took it to a shop and the mechanic replaced the dying fuel pump. my car ran very nicely for about 6 months and started showing hints of hesitation, then while driving on a rainy day, my car began hesitating a whole lot and it couldn't really get anywhere, so i had a tow truck come and take it back home. the next morning i tried driving it and ran just fine! i don't get it, so i took it to a shop and the mechanic couldn't notice anything! *sigh* also, my engine lags while starting;i t's weird because it usually happens on warm and sunny days, around 70+ F degrees, i don't know if it's due to the crankshaft or starter, or something. so, i was wondering, what causes the random and mysterious hesitations and rough start ups of my engine and what can be done to fix these problems? i highly appreciate any feedback, thanks.
