Do you have a BOV?

Does it close after dumping?

Do you have any air leaks?

Check all the vacuum pipes and make sure they are connected.

Some more info on your mods and engine then everyone can help you.

:wink:

When was your car last serviced? I had a similar problem until my petrol filter was replaced.

It's probably plugs or coil packs though.
Diesel power, hmm, yes, I think I'll have some of that.
