Hi, My slow down 7-12cly was coming on and off for a while and then mostly on, even first starting in the morning. The car runs good, but always idle up and down and dies often. I have pre-cats and testpipes with no mufflers. I disconnected the connection from the thermocouple to the ballast (right side) so that the light for the slow down will not come on, the car runs very good, no funny idle, and it never dies not even a single time driving it for 6 hours in the back road/freeway stop and go situations. Just want to share this experience. thanks for any inputs. Jr ps. I did remove the side strakes, but I think I will put it back. It looks good (modern look), but it's missing the classic lines testarossa was known for (except going full KOENIG body update). plus the wifes likes it original looks. You can see my car in the Northern California section ( Bodega drives).
