Cold Engine woes
What would make an LT1 sound like it has a humongous when it is cold, but idles normal when warm. The car also wants to pop when cold. The car has a new Opti, new cts, new plugs, and a new coil and wire. No SES light and It did not do this last winter, so this is something all new. Is it possible I have an IAC about to go? Thanks for the help.
