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) |

So now she's running pretty sweet. I am hiving a high idle issue. It idles at around 1600 rpm. It feels like the adjustment screw on the intake is mostly all the way in and I get no change from turning the adjuster on the computer. I checked for vacuum leaks with map gas but found nothing. I'm going to fiddle with the TPS some more.
Any other ideas? Maybe check the timing again? Maybe the advance is sticky? (IMG:style_emoticons/default/blink.gif) |

Checked the AAR? |
