If it were mine, I would go to www.cruiser54.com and complete tips 1 through 5 before doing anything else. Don't need a mechanic to do them either.

No, let me fix that for you:
3 different Mechanics parts-swapping morons Have replaced everything on it.
Trust nothing those idiots did. Nothing. Assume nothing they did was right. Nothing. Clear the history completely out of your mind.
Start over, troubleshoot systematically. Clean slate. Focus on the symptoms, and do not rule out anything or skip anything based on past actions by these clowns.

My knowledge of the early XJ is limited, but the 2 "high probability" issues that I would be concerned with
1) an open wire or connector fail somewhere
2) a short circuit in a sensor or its wiring..sensors are connected directly to PCM and a direct short to the PCM is not good
