Do a quick TPS check and see if it's in the correct position, they gradually break down and a misfire at any speed is one symptom, but the main symptom would be rough or jerky running at low speeds where you'd need to use more clutch and throttle to compensate. It's something that will take a minute to check, and needs to be ruled out.
Also, when was the last time you changed/cleaned your air filter? A badly clogged paper air filter for example will eventually affect running. K&N filters tend to be a lot more forgiving as they let more air through but they can still get dirty as well.
It runs ok below 3k, idles fine.
New air filter 500 miles ago
Thanks for the advise from everyone i will do the TPS and fingers crossed it is this.
