I have searched and asked before, but every answer is vague. I know that you have to hook up the inductive loop on the first coil wire, that its 15*, disconnect the tps long wire, blah blah. But, what is the complete correct sequence?

Before you begin, do you back out the idle screw on the IACV and set the CAS to the middle position?

Which do you do first Idle or Timing?

to adjust Idle does the TPS have to be disconnected? Does the brown plug?

Do you reconnect the brown plug on the IACV before you time it?

Do you reset the ECU at all?

I'm Prolly overthinking it, but my car feels off ever since it started getting colder, I checked for all leaks, low boost, high boost, manifold. I just want to make sure my timing is right.

Did i say soemthing taboo?? Or does no one really know? The FSM has procedures, but its for the 26. I didnt know if it was different sorta like what sensor you unplug like on the 25 vs the 20.
