Hi,

My diesel saab 9.3 1.9 loses power at lower revs (<2,500) All's well when the turbo engages until I change up a gear.

The independent garage says they've checked all the obvious things and that the diagnostics and emissions are OK.

Should I get a Saab garage to run some diagnostics, or is there some straightforward answer?

The symtoms are very similar to the failure of an injector last year, but the garage says that's not the issue.

I use manly top grade fuel, and have put a bottle of Wynns injector cleaner into a half full tank with no discernable improvement.

Thanks.

Hassall
