So I have had this problem since my trip to the Fall Fling last October. The jeep has a rough and high idle and is stuttering bad ~2000 rpm. Running really rich also.
90 XJ, AW4, 4.7 stroker from Titan. 24# mustang injectors. Ran great for 30k
New plugs (gapped), new cap, new rotor, new fuel filter, new 02 sensor, new cat.
I bought a Snap-On scanner to help me out and this is the info it is giving me.
RPM 1000
o2 voltage .12 @2k RPM its .2-.33
INJ (ms) 6.4 @2k RPM its 12-14
Loop Status, open
exhaust, rich
ST fuel trim, 128
Lt Fuel Trim, 128
MAP Sensor Voltage 1.5
MAP (KPa) 39
Man Vac (KPa) 60
Baro Pres (KPa) 100
TPS (v) .78
Throttle % - 16
Throttle SW - closed
Fuel Sync - flutters between +/-
Spark ADV 14* and then at 2k its 30-44
EGR is usually off and then after its stutters it will come on and then go back off.
I haven't done a compression test.
:helpme: Any help is greatly appreciated and if any more info or data is needed I will get it as quickly as possible. This has really been driving me mad and I am sure it is something retardedly simple and easy.
