Engune idle speed is not adjustablle! That screw is only a throttle stop, ecm has control over idle through IAC valve!!
Thanks a bunch
There are 5 wires running to two separate plugs, which one is negative, and do I pierce the wire?
The white wire with the pnk/blk, the other white wire is a digital signal for the instrument cluster, if the tach is digital use that one.
