the car is pretty original 74' 1.8 with the original FI.
It started to run poorly when hot, she took it to a shop, and they said it needed new points. They replaced those but later it continued to run poorly even cold. last time she drove it, it died shortly after leaving. She got a 123 Ignition distributor, so I went over to help put it in. I'm not a mechanic but have owned 914's since 1977. most of them with carbs not FI We pulled the #1 plug and it was extremely sooty. I guess we need to put the distributor in and see how it runs but I'm leery that is going to fix the running so rich issue. Any thoughts or direction would be greatly appreciated. |

Any thoughts or direction would be greatly appreciated. you just got to be methodical. testing all components. instead of guessing. a good place to start is with the old VW tech literature used by shops back in the day. jeff bowlsby has some of these on his website and you can download them. pretty handy to have. its not that complicated a system. you can get your head around L jet reasonably easily. its a lot simpler than D jet. a lot. links to bowlsby website. this one is not a bad one. generic VW early L jet troubleshooting guide. https://bowlsby.net/914/Classic/zTN_Man12.pdf |
