I drive '94 teg LS/VTEC and since the hybrid was built I haveproblem with idle. It's at the level of 1200 rpm and stays at that level no matter if car is warm or cold (in cold it is only 100-200 rpm higher). Throttle seems to be closed, but effect still exists and makes me nervous. I tied to adjust revs by means of adjustment screw, but screw is on the maximum close limit.

During driving I don't feel negative effects of that idle.

Please let me know what can I do? Any ideas?
