also when it bogs down its quite like a miss fire or off a cylinder ??????????? help still needed.

Just a thought..but you could try checking the throttle body are tight against the intake manifold and the jubilee clips are secure.

Does sound like a faulty TPS.

[ss29]

I'll check them, its at its worst when im in 6th and just cruising along about 4000rpm and when i accellerate may it be hard or gentle at 4500rpm it just starts to bog down and vibrate like its of a cylinder and it doesnt want to rev and its very slow to pull out of it until about 5500rpm and then its fine again

[den]

Had same on my 996bp turned out to be a faulty TPS as rockhopper sugested

[ss29]

den, was it expensive, easy to fit yourself ? cheers

[den]

Dont know how much it was as the dealer had replaced the fuel pump first saying that was the problem so I never got charged for it the pump was around £90 so I would imagine the pot was a lot less!! the dealer set everything up for me

[rockhopper]

I think a TPS is about £120 ish. Sorry.....

[ss29]

rockhopper, do you know is this a direct replacement part that i can fit myself or does it need to be a dealer job, £120 ouch but if it cures it, its well worth it, cheers

Fitting/adjusting a TPS is not "hard" per se. But it is an almighty fiddle. I've done it on a 2 valver & it does improve running markedly.
Check out the FIM website for instructions.
