I finaly chased down idle miss and stumble.

After replacing:ignition wires, plugs,dist.caps and rotors, temp sensors, R&R intake, cleaned fuel injectors and clean grounds, I was ready to accept the poor idle and enjoy the car.
Imo000 (Rennlist member) THANKS, supplied/borrowed a known good MAS and problem fixed. Today I received a Repaired Calibrated MAS from JDS Porsche Canadian representative(http://www.dsylva-tech.ca/) Mark and throtle response is more crisp and idles smooooth.
Prior to actauly trying Imo000 MAS I also started to experience lack of power and flat spots on acceleration. The vehicle was not fun to drive at all!
I strongly suggest to replace your MAS, if aged or at least try a known good unit before spending huge amounts of money on ignition/fuel stuff. My MAS had 120,OOO miles.
The good is now I have a baseline on routine maintenance
items.

Thanks

Yes, Mark is a great guy !

He will have rebuilt MAFs and LH ECUs in stock for Canadian owners.

I have a D'Sylva chip in my E34 BMW daily driver. Mark has been a tremendous asset to the BMW community and it's great to see him working with the Shark Society......
