V10 cold start idle surging
On my 2000 v10 ex..when I start it when its cold.the idle surges up and down until it warms up then idle is smooth. It has done it since I've had it and have owned it for 2 years. I have recently replaced plugs,cop's,fuel pump,fuel filter. (Not for this idle issue) fuel pump died on me. Truck has 160k miles..tried pulling codes and there are no pending codes.anyone have any thoughts? Thanks everyone!

Idle Air Control valve possibly, it helps to regulate the idle on a cold engine and they do get gunked up, a good cleaning may restore a steady idle.
There is a how-to up in the TECH FOLDER at the top of the EX forum page.
