All,
Looking for some diagnostic assistance for my stock '74 2.0 with FI. I was driving back to the Truckee area from Reno on Sunday and the car began stuttering. It happened for a quarter mile or so then stopped. I took it easy the last 20 miles. It was a very hot day. I left Truckee for Sacramento this morning and the car ran great until I got within 25 miles of home when it started missing/stuttering again. It is also very hot in Sacramento. I've never had this experience in the 5 years since I've owned this car. I always try and drive it in cooler weather but there was a Porsche event in Reno I wanted to attend this past Sunday. Any ideas? Thanks, Jack |

A factory fuel filter was not handy so I used a metal can type with the same inlet and outlet size. Worked just fine until the first real warm day in spring in bumper to bumper traffic. The engine would miss badly. I pulled off and let it cool down a while and then headed home. Fine on the highway. A proper fuel filter cured the problem which was heat boiling the fuel in the metal filter. |
