    Speedo bounces around erratically. Driving at constant speed, and it will drop back down and return to approximate speed. When driving around 25-30 mph, I feel a clunk/ downshift at odd times. Had speed sensor checked--it's ok. Had speedo gauge checked, and its ok. Mechanic is thinking may be electrical issue--odometer doesn't measure accurate mile (about .2 short every mile).
    Any ideas? Would welcome any help you can offer-- I know NOTHING about engines, but don't want to spend extra $$$ having mechanic checking all the wiring in the Jeep if that's not the problem. Thanks!

    Welcome! Not sure whether '02 Liberty still use speedometer cables but I've seen worn out cables or cables that need some lube have similar issues.
