What did you find out ???
I have the same thing, Runs good to 3000 rpm and stumbles to 4000 rpm then runs like new. If I increase throttle early (before 4000 rpm) it makes the acceleration worse. About half throttle seems to be the best.
I have new fuel pumps, Checked the fuel trims, fuel pressure stays up at the fuel rail through the rpm range. I runs so good and throttle response is perfect above 4000 rpm. TPS is reading correct also. No fault codes
This is a '99 XJR.
Help!
Thanks,
David
