In the quest for a perfect running 914 im getting oh so close. In the past I have replaced the tps with a new one that fixed the severe bucking/hesitation. The car ran so much better after that. What I am trying to figure out now is a random hesitation/hiccup that happens mostly during steady throttle when I am cruising on a highway. If I drive 30 miles it might happen once or twice. It seems pretty minor compared to the bucking I was having with the old tps. If I recall it has had this hesitation since I have owned the car for the last 3 years. I know the distributor does have a pertronix module in it. Ive recently changed replaced a few things listed below but still have that little hiccup. What would you guys investigate next?
Replaced: Fuel pump/filter Installed SS lines plugs, wires, rotor, (cap still looked new) tps sensor |

I had a similar problem last year. Suggestion was to drop a couple dabs of oil into the cotton at the top of the disty shaft, to ensure the centrifugal weights weren't stuck.
Seemed to help, but didn't totally resolve the rare burp (usually an hour away from home, causing the blood pressure and heart rate to rise...) |

I tried that a little bit ago and the same as yours it did seem like it helped some. i don't recall there being cotton in there though (IMG:style_emoticons/default/sad.gif) . I just put a few drops down the inside of the shaft |
