1990 245 DL.

Hello Bricksters

My 90 245 is idling rough and sometimes hesitates a bit on take off. I have pulled codes 2-3-2 and 2-3-1 from the ECU. I removed the IAC and gave it 12 VDC and the shutter rotates. However, and this is my question, when the IAC is un powered there is a small gap that allows air to pass at all times. Is this normal? I never had the IAC out before.

Any information is appreciated.

Fred
