Whilst driving my car i am experiencing changes in the power.
At times In 4th and 5th gear you hit 3000 revs and then it drops to 2500 or below and surges up and down.
At times In 2nd it randomly shoots up the revs really fast and then dies off to low revs. (sometimes)
The power delivery is slow and patchy at times and its a bit noisy.
The Car etc:
2.0DTI 53 plate Hatch
Had a OIl change and Fuel Filter change today
Veccy Air intake pipe and Airbox derestriction.
Many Thanks for any help!!
