Lack of pace

[fastwunz]

My clio seems to run out of acceleratory puff between 3-4000rpm at the mo. Have recently replaced the head. It still accelerates but no where near as much as it should. Is it worth replacing the fuel filter - think its the original?

couldnt hurt to change filters but if the head has been recently replaced id leave it for a couple hundrd miles before doing anything about it. Itll prob slacken off (well, mine did anyway after reconditioning and having the head tightened down).

do a leakdown test to see if your heads on properly.

that would be a start-compression and leak test on all cylinders.
