I just bough my first jaguar, 95 XJS 4.0 AJ16, with 175k, Need a transmission, found a used ZF for a good price, car now drives, Next problem when driving engine has lack of power at times once warm up, driving you can feel engine stall the power returns. check ODB codes P0300 random miss fire.
also fuel gauge moves a lot when driving, sometimes stable, Once you make a turn or hit a bump in the road gauge goes to empty low fuel light comes on then goes out,
I have change fuel filter, New plugs, valve cover gasket and rings, an one new coil pack,
any ideals ??

Some time ago, I bought a real nice 85 Ford F150 4x4. Test drive was fine.
Only after it lived with us did similar things start to happen.


I applied the jiggle technique under the hood with he engine running. With due care,as the whirling fan was there!!!


Yahoo, wiggled a black bundle and the engine stumbled. tracked it down and verified, a ground indeed. I bridged the suspect connector and made up redundant ground.


Solved, purred til the day it left. Miss that neat old slick black truck.

A while back my AJ16 was going out when hitting a bump in the road. It was the inertia switch wiring on the passenger footwell
