So I got my car back from the local Porsche shop and installed a rebuilt MPS from Bowlsby but the car is still not running right. Flat spots and intermittent dead fire misses. She starts right up, idles well and drives ok but when you get on it it has intermittent flat spots and when shes just cruising it misses once and a while. Seems like the advance is not ramping up like it should. Also, the mechanic left a vacuum line off the distributor. The line from the inboard connection on the pot is hooked up but the outside one is off. I understand that one of these is advance and one is retard.
Just need a list of crap to check (IMG:style_emoticons/default/biggrin.gif) |

I removed my AAR long ago....it's not really needed.
Does the air bypass screw do anything now? Can you tune the idle with it? |

It's screwed pretty far in. to the point that I have to use a screw driver (I.E. remove the air cleaner) to adjust it in. If by "now" you mean with the AAR removed, I haven't tried messing with it yet. In chilly Maryland I don't need the AAR? Do I plug the back of the 5th injector? |

By "now" he means you have eliminated once source of a vaccum leak. Next: Can you adjust the idle speed with a screwdriver. Stay focused...don't worry about the AAR right now. |
