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 ??
