#3 of 7 XK8 engine stuttering by charlie193 Mar 07, 2006 (3:57 pm)
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
#4 of 7 Stalls while moving by svp Jun 18, 2007 (9:08 pm)
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. Replies to this message: Mr_Shiftright (Jun 19, 2007 6:39 am)

Replying to: svp (Jun 18, 2007 9:08 pm) The gearbox? That's a weird diagnosis!   Anyway, this sounds like a computer problem..a total misfire...I just can't think of any other component that has control of that many functions all at once. 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.

Replying to: charlie193 (Mar 03, 2006 3:25 am) Can you tell me the mechanic who reprogrammed your computer to take care of the stutter? I have a 1998 SK8 with the same problem and live here at Lake Tapps outside of Auburn. Replies to this message: theflyer (Sep 03, 2008 3:08 pm)

Replying to: rshoemaker (Nov 23, 2007 8:50 pm) I just bought a 2003 XKR (9000 miles) with this stuttering problem. Worse case at 1200-1500 RPM in any gear but more pronounced when on a slight incline or flat road. Two dealers (and $ 3000.00) with no luck. This car also shifts very hard compared to my 1998 XJR that runs beautifully.   Anybody no of a dealer who knows how to fix this ? The car is of little use running the way it does.
