Before I go and spend some of the rare folding stuff...
My 2001 Astra diesel (2.0dti) is suffering from power loss at around
2500 rpm - at these revs the acceleration reduces but the rev's climb still. My current number 1 suspect is the air mass sensor as when I took it off last night to see if there was anything obvious when I replaced it for a while the fault cleared itself. (She's never run low on oil since I've had her and I've done around 40k miles - this fault has just started to occur in the last few days).
Anyone think of anything else I need to check before I replace this bit?
TIA
Richard.
