I had a mild annoying problem one time which was solved by tightening every single inlet manifold nut ... again.
Just worth a go, very quick.

Hi
Roger when Checking Manifold Just To Double Check WITH the ENGINE COLD SPRAY MANIFOLD GASKETS WITH WASHING UP LIQUID AND WATER START ENGINE AND CAREFULLY LOOK FOR LEAKS AND LOOK UNDERNEATH THE MANIFOLD AS THE ENGINE HEATS UP THERE MAYBE A SMALL CRACK OR SOMETHING THE SYSTEM IS A CLOSED LOOP SYSTEM SO ANY SMALL LEAKS CAN AFFECT DRIVABILITY THE ONLY OTHER OPTION I THINK WOULD BE TO BOOK THE CAR IN AT A BOSCH SEVICE STATION I SEE THERE IS ONE CALLED THE FOUR SEASONS SERVICE STATION IN ROCHESTER THEY WILL BE ABLE TO SORT THE PROBLEM OUT WITHOUT YOU TRYING DIFFERENT PARTS AND HAVE THE KNOWHOW I USED TO WORK FOR THEM A FEW YEARS AGO

One local Bosch service centre frankly admitted they just did routine servicing. They recommended the local genius Medway Security Service who has ALL the diagnostic stuff. He ran a mile at the mention of a pre OBDII problem. Not even interested in looking.

They are the chaps who very honestly admitted that all they did was routine servicing! Far better than taking the car in and getting nowhere and giving me a big bill.

.................at least they were honest!

I'm fairly sure this has probably been asked before but have you had a compression test done since the HG was done?

The reason i ask is a friend of mine who owns a Rover 820 Vitesse Sport turbo (the 200bhp jobby) had a similar problem recently. In fairness it seemed to be generally down on power, not quite as smooth as it should be and a few other minor things like noisy valve train etc.
Being the sort of bloke he is, he stripped and rebuilt the head and found during the process the exhaust valves weren't in the best of shape. In fact they were almost oval, mainly because they had got extremely hot at some point.

Given the fact you've tried all the other obvious stuff i'm beginning to wonder if there was something like this that was missed by the garage that did the HG originally and just couldn't work it out.

I know that's a bit of a drastic measure to take, removing the head again and checking but this has been rumbling on for many moons now. Perhaps someone else could give it some thought and see what they think, it could perhaps be worth a try.
