so... it idles high until your car warms up and then it goes nuts?

This sort of thing is common after doing major engine work. You crossed up the wires for your EACV and the Evaporative Purge Solenoid. They have the same connector and are very close together on your engine harness. One of the wires on the EACV connector is blue with a yellow stripe. The purge control has a red wire. Both have a yellow wire with a black stripe (power +).

Makes a great practical joke. Amuse your friends, and you'll surely be loved by all! :nono: ...either that, or for the rest of your life you'll be ducking and dodging sharks with laser beams.

As for the timing cover idea... I have no idea what you're talking about. When what hits? Push on a who? What engine noise? What's moving against the cover and why would you push on it? If you don't, it doesn't rub? Wha?:dunno:
