alright i just dont get this whole thing... my jeep started to stutter.. i figured out it was an injector... welll i pulled off all my injectors to clean them out well what i found is 2 different types of injectors.. i had 3 stock bendix injectors AND 3 2001 style injectors with the flanged end and a plastic nozzle... now this set up has worked in my jeep since ive owned it (8 months) just fine.. i went to merrit island refuge which is in florida and alot of the trails are washboard type trails.. goin there my xj ran fine like it always did than on the way back it started stuttering.. being my xj is 22 years old i decided to clean injectors/ rail.. well.. which is when i found the 2 different types of injectors.. after i clean the injector it runs good but after like 3 min of driving it goes back to stuttering.. any idea of why this is happening???? im getting pretty frustrated with this..

if u never replaced crank sensor, do that, also check fuel pressure. Crank sensor seems to act worse when warmed up.

the thing is though it still runs like crap in the morning when the engine is cold....
