Then test if other pin(colour?,black/blue i think) is continuous back to ecu pin A9 on OBD1,A12 on OBD2.

A quick test is pull the A plug on ecu off turn ign on & ground the IACV wire on & off, & see if u can hear the IACV click each time u ground it.
ok i'll try that... hmmm... if it doesn't click does that mean i'll need a new iacv?
and if it clicks does that mean it works...

thanks
