High idle and TPS code

[RadRacer]

Alright, every once in a while when I start my car it'll idle high at around 2-3K RPMs. It'll also throw the SES light and it comes back with a TPS code. Car runs perfect, except for the high idle. It goes away usually within a minute, and doesn't do it again that run. It doesn't do it after it's warmed up, it's just random cold starts. I replaced my TPS, so I'm thinking it's a vacuum leak somewhere; that rubber elbow that goes onto the TB is rigged on ATM because I can't find it anywhere, and I'm thinking that might be my problem. Either that or a bad IAC, what do you guys think? I'm hoping to get my scanner sometime soon, and hopefully get some sensor readings when it does it.
