Definately NOT normal. Should be about 95`ems top knock. Not a dragster but does sound wrong.

Could be something as simple (and cheap) as blocked/dirty fuel air filters, or something much worse (expensive). Any smoke? Whistling noises? Any other symptoms?

No black smoke to speak of, if i use the kick down on auto box there is the slightest amount but nothing to worrie about, its had a service less than 1000 miles ago and the filter looks new.

Just had a similar problem to this, and the good old boys on here helped me sort it. I changed the fuel filter, the wrong one had been fitted, I also re-connected the MAP sensor pipe to the fuel filter assembly, it transformed the car. Hope this helps.

Walk away, there are so many out there it would be foolish to buy one that has a fault to start with. They certainly dont fly but top speed should be about 90 ish. Sounds like it may be in "get me home" mode.

Check the pipe from the MAP sensor bolted to the fuel filter, is connected under manifold, has no splits and is not blocked. Check that manifold outlet is not blocked and MAP sensor inlet is clear. sounds like you have no boost fuelling.

Is it only like it when its cold or does it get better as the vehicle warms up?
