Very high idle, sorta, just appeared yesterday
Well, I wanted to check for a part number on the ECU connector.... so I disconnected it, saw nothing useful, and reconnected it.
Now, since then, when the truck is cold it idles at almost 2k RPM. As it warms up, the idle kicks down in 250-300rpm increments and eventually ends up back at the usual 750rpm. Prior to this, it ALWAYS idled at 750rpm all the time.
Is something wrong, or WAS something wrong and I am back to normal now?
My oil line fix
My 100k stopped odometer fix
Brace for impact, I'm in a "modifying mood". Massive thread count inbound.
