I’ve been chasing a bad miss on my 1975 914 for some time and thought it might be my Pertronix Ignitor ignition unit. When I tried to replace it the new one didn’t fit. So, went back to points and condenser. I may have the wrong points and condenser, because it wouldn’t start..
After some detective work I think a previous owner installed a distributor out of a 1975-1976 VW bus! The reason I think this is true is because when I google my current Bosch Distributor number, 231 176 048 I’m getting an eBay listing for a reconditioned VW bus distributor. My question is: is there a cross reference where I could put in Bosch Distributor #231 176 048 and find what vehicles this was put in so I can get the right points and condenser? Long term, I will replace this distributor with a correct Porsche 914 one, but I want to get back on the road now and enjoy the beautiful Pacific NW winter weather (IMG:style_emoticons/default/biggrin.gif) Thx, PDXBob |

When I tried to replace it the new one didn’t fit. So, went back to points and condenser. I may have the wrong points and condenser, because it wouldn’t start.. Firstly a Pertronix unit won't create a miss ..they just work or don't ... (IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/agree.gif) An electronic points replacement ignitor (this is what the Pertronix is) CAN be intermittent, MIGHT create a miss but this is FREAKING RARE! What those critters USUALLY do is overheat. Once overheated they flat don't work. If this happens on 635 in Dallas rush hour you are SCREWED. Dead puppy, wherever you are! Once you let them cool down, they MAGICALLY work again: right up the point of overheat... Years back we could buy GOOD "component cooler" which was normally refrigerant. You could FORCE cool the item and pinpoint your issue. I always kept a can in stock. The new "environmentally friendly" component cooler doesn't work nearly as well today. This is why I posted what I did. Porschetub's RIGHT! I'd bet BIG money the ignitor is not the source of your miss. |
