so....

the 4 th iacv died now in my car.

what could be a reason for this?
the last and brand new one from honda i mounted without water hose connections.

now i unplugged the electrical connection and raised the idle rpm via screw at throttle body. but the engine contral light in the tacho is on now.

is that the only effect? and that the engine takes gas not that smooth? a bit rucky now. like a race car.....

if nothin can happen to the engine i won t buy a new one.....

but i really look forward to your experiences and knowledge now.

thanks
