[QUOTE="dvng, post: 43476, member: 196"] The ecu is not the problem since yours is probably on the Motronic 1.3. The main cause could be the throttle position switch, clog ICV or your CO value is too high. The problem is the m20 engine requires experience tuning, dont just increase the airflow for higher idle rpm this will cause the engine to idle hunt. Keep Co value between 1.0 and 1.5%. [/QUOTE]
