Jeep liberty 0., engine light on, stalls out at low rpm, slow accel, uneven revs. at constant speed, engine revs and jumps.
The ignition timing is off.
The ECM (Elctronic Control Module) is responsible for that.
Take the Liberty to AutoZone to have them scan the PCM code (free) and ask for an explanation print-out (also free). You might want them to clear the error code afterwards, too (yes, free).
Let us know what the codes are and a summary of the print-out.
