87/4.0/puegot Recent tune up, new cps, swapped icm and coil from the jy didn't help, adjusted tps and tried a new tps, new fuel pump filter and relay, new alt battery cables and upgraded grounds with old battery cables as well as upgrading the alt charging wire and the wire that goes to the power distrobution thingy from the battery, and pretty much did everything in the renx files. It feels like the jeep hickups. It happens mostly during light acceleration/cruising but occasionally happens during hard acceleration. It used to do it really bad to the point that the jeep would stall for a second or two and if I got into the gas pretty good it would turn back on. It's turned off completely maybe a dozen times in the year and a half I've owned it. After all the upgrades I've done it hasn't turned off all the way in a while, it does just slight hickups now. It used to do it more in the summer but now it pretty much does it the same in the cold weather as much as the hot weather. Today I unlpugged the o2 sensor and drove around like that and it feels exactly the same as plugged in. It goes up and down in idle maybe 100 or 200 rpm's when it's cold and it pretty much goes away when it's warm. It doesn't have a tach so I can't tell the exact numbers but that doesn't bother me that much. The hickuping/jerking while driving is what bothers me. I haven't tested the o2 sensor yet but it looks like it's possibly been replaced by the po. When I first got the jeep I figured it wouldn't pass smog legitimately so the guy that bootlegged it told me it was running rich. The cat fell to pieces soon after and it's just straight piped now until I have to smog it again in July. I would really like to get rid of this hickup. It bugs the hell out of me. I've had two other renix xj's and they didn't do this to me. I wouldn't be opposed to taking it to a mechanic if anyone knows of a mechanic that can scan a renix xj or that can give me some guidance I would appreciate it. I'm thinking to get a complete set of map, distributor, cts, iat from the jy on half off day and swap them one at a time to see if it helps and bypassing the c101 connector but that seems like a bear. The grounds seem solid. All the sensors are reading 2.5 ohms. Please give me some guidance!
