Hello, I have a CC and a CS each, both from 1991 with a 2.3L engine without turbo and with automatic transmission. Both have the same problem: the cars jerk and crawl – if the cars have stood longer (in cold weather enough also over night), then they start in the morning with unround motor run and a start on “D” is only very slow and with interruptions possible, often the engine also dies off! In the reverse the phenomenon is by far not so pronounced After a few minutes the symptoms disappear. Then I can leave immediately after 3-4 hours of rest over the day without the phenomenon again. A “Saab-Fachwerksatt” already cost me 800€ for an unsuccessful troubleshooting! LMM, throttle valve and temperature sensor as well as petrol pump were tested, everything without finding out. Who can help?
