Hey guys, I was testing out a used ECU I just got for the car. When I turn the ignition on-the idle motor stays silent for about 5 seconds-then slowly comes to a strong hum. And upon inspection, the orifice will stay open about 3/4 of the way whether the micro switch is engaged or not, it will not change position no matter what...I'm still confident that the motor I'm using is still good since a quick touch of voltage and it opens/closes fully. I switched the inline diode and it didn't seem to make any difference. So...,Is this second ECU I'm using also bad, or have I overlooked something else? Hopefully I can get this car back to idling well! Thanks for any help!-----Dani B. #5003 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
