820 Vitesse problem

Don't also forget to check...

Thermostat & connections (causes some funnies) Crankcase sensor (goes intermittant) Throttle body stepper motor (causes even more funnies)

My be a burnt out exhaust valve. I've just changed one on mine. Garage wanted £500. Get a compression check. If you do it yourself try to get the later Klinger gasket.

Could be fuel cut..... if any of the pressure hose going to the turbo wastegate actuator has holed it will cause 'bucking' *ONLY* when the engine is under heavy load. I would look here first..... based on your symptoms... thats if it bucks!

Turbo is at front of engine, small cylinder to its rear with a rod sticking out one end and a tube out the other, thats the tube to look at......

Thanks for the ideas everyone - I'll check them out over the weekend.

symptoms...

On some engines (in particular K series) if there are problems with exhust valves, addding a shot of redex to a tank of petrol may do the trick.

Just a thought

Thanks, We've already tried Redex fuel treatment, and then STP injector cleaner. Neither made any difference at all. Hose to wastegate actuator looks fine, as do all others we can get at. Electrical connector at thermostat was cracked so I replaced that with one from an old Toyota wiring loom I had lying around, but it made no differnce either. Aaron.

Burnt out exhaust valves are common on the T-Series engine. Get the compressions checked. Rover dealers charge £26 for a full diagnosis session and if your lucky they will even wash and valet the car for you.

What about the compression test?

That will tell a lot
