Hello all,
I'm experiencing rough engine startup on my 1989 928 S4 ROW. The engine fires up correctly after less than 3 turns but has a rough idle for 10-15 seconds.
The idle stabilizes and gets smooth after that period of time or just after I depress the accelerator pedal to give it some gas. I also feel that the engine delivers less power going from idle to 2000 rpm on the first A/T gear. Above 2000 rpm, all the power appears to be there.
Anybody has a clue as to what causes that?
Regards.
M. Tremblay
