Re: 147 acceleration
you have the 2 litre right? (just an educated guess)
i would suggest a throttle and ECU reset... should help cure it. ...
1) Disconnect the negative lead from the battery and leave it disconnected for 15 mins or so (you could just short the pos and neg cables but i dont like to do this)
2)Re-connect the battery neg lead.
3)Put key in ignition, turn to MAR and wait 2-3 mins.
4)Turn off the ignition, but not remove the key, wait 2-3 mins.
5)TuStart the engine up but DO NOT touch the accelerator.
6)Let it idle for 10 minutes.
7)take her for a little drive (i usually do about 10 miles)
sprinted - more responsive end result but lower MPG
casual - less responsive end result but more economical (lower performance)
in all fairness whichever method of driving you choose wont matter a great deal as the ECU will 'learn' your driving style and adjust accordingly anyway. i prefer to go for a very sprinted drive!
see if that helps things at all.
