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 |
