Do you have a late 90s Jaguar XK8 that has intermittent multi-cylinder misfires, crank and/or cam position sensor DTCs, runs rich, hard to start while cold or runs well then runs poor then runs well again in the same drive cycle? It all boils down to bad solder joints in the ECU, as we have learned on Andy's 1997 XK8, saving him a very LARGE amount of money from the dealer!
