HELP! VT Berlina surging problem.

[edgy]

Hey all!

Had this problem for over a month now and it's really ticking me off. Seems fine when running cold but once up to operating temp it will stuggle especially uphill, sort of hard to explain but say you'd be coasting along and go to accelerate the car will sort of hesitate and struggle to respond at times.

It has recently had new leads, plugs, fuel pump, coil packs and dfi module but none of this has fixed the problem.
It's getting new engine mounts next week, do they have anything to do with this kind of issue tho?
Any help or suggestions on what to try next would be appriciated!

by struggle do you mean it has no power or that it shudders?

Like i said its hard describing, it's sort of both doesn't have the initial power, shudders, then i'll accelerated a bit harder and it'll take off like it should.

if you put into gear with foot on brake
and lightly accelerate does the car shudder? this is likely to be misfire then

Just gave it a try and nope, feels normal.

right then...
so when you are rolling along at low speeds and stomp the accelerator what happens exactly?
do revs stay low like 2000rpm and it moves really slow or does it just revout and no go anywhere?
also
does it idle rough? e.g. does car shake alot?
