Hello, I have had a large vacuum leak from the throttle body for a while but since i only drive my truck every month or so i haven't messed with it. Today i went to check it out and it turns out the 1227747 ecm is not sending a signal to control the iac. What could be the problem?
Also I cannot for the life of me get my laptop to connect to the ecm. I did the timing patch and ever since then it just says connecting never connected. I have an older ftdi driver from 2009 that i know works. The aldl cable i built used to work fine. The tx/rx lights do not light up when i am trying to connect.
