98 tj 4.0 throwing codes and sputter

[creepytj98]

ok so my jeep has had a sputter FOREVER now. i repaced the gas tank and that helped for about 2 days (it was sucking air between the locking ring and gasket) after i replaced that it ran great but wouldent crank up w/o dumping fuel in the throtle body. it stared shutting off after about 3 min running. i let it sit with the battary disconneced and it stopped shutting off. but now it takes about 6 cranks to get i cranked up. runs good at 1/4 throttle and full throttle but anywhere inbetween ther it sputters and bucks like hell. just got the codes check here they are :bank 1- sensor 2 high voltage(P0138), ingnition\ distributor speed(P0320) and tps(0121) the tps is less than a year old. im guessing i have some wireing issues but im not fimiliar with wireing and have no idea where to start. if anyone has seen this before or could tell me where to start that woukd be great

replace your bank 1 (front 3 cylinders) after cat 02 sensor , replace your crank sensor (p0320 very common and can be your starting problem) replace your map and tps sensor

start there and its a good chance all your probs will be fixed
