    Try resetting the ECU. Either disconnect the positive battery lead for 10 seconds, or pull the main engine fuse for 10 seconds.

    Sorry mate can't help out, but I have the same problem with my VR...It seems to be since I got the lukey 2 1/2'' but it could just be my tranny causing the problems...in 3rd between 90km-70km when I ease off it jumps up and down abit around 1500rpm. Would like to hear from others on these matters aswell...
