Similar to Talat on the Spa thread, my car has developed a problem that may be due to a temporary lack of use.
The car continues to start instantly but will not tick over without throttle assistance and does not run cleanly; cutting out when lifting off the throttle and generally needing to be coaxed along.
I'm not happy driving it like this, it may leave me stranded so I'm trying to eliminate those things that are easily swapped before having it trailored to a garage.
I've swapped the DMA relay and the MAF unit functions correctly, without improvement.
The distributors and leads are all new so should be good (all Porsche), Boxsey has helpfully suggested, among others, the Idle Stabilization valve (is this the MAF unit?).
The fuel filter and presumably fuel pump are potential culprets I guess. Can anyone tell me where they are sited, please? How do i restrict fuel leakage when removing - is it possible to crimp the pipe? Any replies and/or further suggestions of other home checks gratefully received. Ian.
