| Some XK owners report engine hesitation, stuttering and other symptoms of erratic engine operation. Have you had these experiences and solved them, or are you having them now? | |

From new, my 1998 XK8's engine (now 67000 miles) stutters at light acceleration, abt 2200 to 2800 rpm, as when climbing a mild hill or accelerating on a freeway ramp. Jag dlrs check with their computer and tell me 'all is OK', but stuttering persists. When it starts stuttering, heavier throttle eliminates the problem. Other Jag owners tell of the same problem. Symptom seems similar to some other fuel injected engines whose software mapping has errors, surging up and down on power at abt half-second intervals, repeatedly until out of that power band. With a long mild hill, it will persist. Any corrective action available?

I had previously reported a stuttering problem from day one with my1998 XK8, as when climbing an urban long mild hill. Abt 1300-1400 rpm in top gear under load the engine would stutter badly. Heavier throttle would get out of the condition. Dlrs all across the US expressed ignorance and could not duplicate. I found a very capable Jag tech who understood exactly my problem and reprogrammed the Engine Control Computer, which cured the problem. I was told that my car (020160) is in the VIN range wherein the problem exists. Problem solved. Charlie, Seattle |

My 2000 XK8 has a strange problem. 4 or 5 times a year, the car stalls while moving and then will not start. No clicking, no grinding, just nothing. But all the electrical stuff goes nuts -- steering wheel telescoping repeatedly, gas latch poping open, trunk and hood lids popping open. If I tow it home & let it sit for a couple of days, it starts again. It's been to the dealership several times. They said it was the gearbox & changed that. No help. Now they say they cannot find any problem. Does anybody know what is going on with this car? Thanks.

I mean, no one fuse or relay could kill the ignition and work the trunk! One would have to examine the wiring diagram carefully to understand how this all fits together. |
