Hello, hello! The new to me 914 is so rad! Love it... went out for a bit of cruise and about 20+ mins into the drive, while approaching a trafific light ( red ) the car came down to idle and that kept going and poof... stall. It did not start, I blocked the lane and angry SUV's and Tesla's honked at me. I did however get it going again after putting the pedal to the floor while starting and it fired up and drove fine, until... idle at the stop sign. Poof, stall. BUT this time pedal to the floor and fired right up.
Thoughts, where should I begin. I have attached a video of the issue... thanks! Beep Beep. https://www.youtube.com/watch?v=Mx47LENYFuU |

So it takes about 20 min's before this happens? If so I think we can rule out vacuum leaks as that would increase the idle speed. Rule out the TPS idle circuit as that would be wonky warm or cold. Does your ECU have a black know on top. If so that controls the idle circuit. You can figit with that. IIRC, it has 22 clicks rich to lean. If that does nothing check to see.if the vacuum is holding on the MPS. That's also in Blander's D Jet Bible. Once warmed up check the ohm reading on the CHT sender on cylinder 3. The values are also listed in Blander's Bible. If you have L Jet disregard everything I said. Good luck and if it (IMG:style_emoticons/default/sheeplove.gif) with you too much throw a Subaru drive train in it. (IMG:style_emoticons/default/happy11.gif)
