I was on a rolling road with my newly build sr20det engine, to get it optimized, and it done a good dyno with 340 HP at 1 Bar (Arround 14 PSI), but after 10 min in idle after the dyno, it start making a lumpy idle and at arround 2300rpm it jumps between 1900 rpm and 3000 rpm (The timing jumps between 20 and 70 ), and i got a new error indicator in my cluster.

Do anyone have any ideas ?
