2002 Jeep Liberty Repair Question
I'm having problems with my Jeep.
Once it acts up again try to keep it in that bad state so there's a defect to be found, then use a digital voltmeter starting at the battery and working your way toward the starter to find the bad connection. I can send you to a web page describing that procedure in more detail. It's actually pretty easy.
The idle speed problem is due to the Engine Computer losing its memory from the low voltage / bad connection. Once that is fixed I can describe the simple fix to relearn "minimum throttle".
