Engine Performance problem
1997 Rover 6 Series Front Wheel Drive Manual 130000 miles
Hello, I have a Rover 620 sdi I am having problems with my engine flattening out as I reach 2,400 revs. My top speed going downhill is 70 mph and uphill on a good day is 49 mph.
I recently took it to a garage and was told it would have to go on a diognostic machine. Once it was returned I was told that my mass air flow sensor needed changing.
Although I ordered and changed it myself I am still experiencing this problem. Now I'm being told by the garage that it could be the engine managment system, fuel filter, or even the turbo are knackered.
