Well, new leads didn't make any difference at all! Not a jot. Will get my multimeter on the coil tomorrow to see if that is within range. It's the OEM Bosch unit so should still be on good shape after just 75k but who knows!

I have new gearbox oil due tomorrow too, I read recently that a guy with a B200FT in a 940 cured his hesitation issues with fresh gearbox oil, a long shot but something that needs doing anyway, so we will see. New fuel filter and a bottle of Forte will be going in too. Beyond that I'm somewhat stumped!

One thought is that I need to make sure the vac pipe is on the EZK and in good order. I should check ECU and EZK for electrical integrity too and reflow any dry joints. Not altogether sure where to find the boards but will hunt them out!
