ok i had my motor rebuilt and pretty much stock except it is bored.06 and have 4.0 throttle body and cold air intake. my problem is it seems my jeep doesnt get the fuel it needs. it seems to run smooth and on a flat or going downhill its not bad at all. the problem is it doesnt wanna pickup speed at all going uphill and even on flats it just doesnt seem right either although it does pickup smoother. i have the standard 5 speed and at time of motor rebuild i had a new clutch kit put in and also a new fuel pump. i also just recently replaced the fuel filter which helped out a bit but its still not what it should be. i did the 4.0 tb mod after the breakin and motor rebuild and that at least judging by drivability has helped. i just dont know what to change thats going to fix my problem. theres got to be a comp somewheres right? could this be a case of the comp not giving motor enough gass and require a new comp or burned chip for mine? the rebuilder used the original fuel injectors he said he cleaned them out good and such could bigger injectors help? i got a new sending unit and fuel pump from ebay and the ad gave it for years of i think 85 to 95 could this be a pump for the carberated engine and not be flowing enough for what i need? i really dont know where to look or how to tell what the problem is. i could just replace stuff and see what works but $ tight and i got break work on my car that needs done by end of june so dont wanna throw any $ at useless things. the idle is also a lil funky sometimes it idles rough and other times it idles fine. this really had me dragged down as the jeep was so much fun to ride in and now its like only way i have any power at all is over 3000 rpms and then the motor really seems to do well and speed really picks up after that but in 5th gear i cant seem to get over 3000 rpms and only at maybe 70 mph so as soon as i hit a slight incline its like hitting a brick wall so any thruway driving is almost out of luck as the norm here in ny is 75-80mph. (i know speed limit is 65 but ya do 65 to 70 and its like everyones trying to run ya over) now i know my jeep wont do the 0-60 in 4 sec and thats not what im looking for but it shouldnt be this hard to get up to speed and i shouldnt havta over rev it to get there niether. oh yeah and one other thing i got a 91 with the 2.5l 4 cyl.
