Hey guys, having some trouble lately with a high idle. While driving, I've noticed that the idle switches from the normal ~600rpm to around 2000rpm. If I stop driving and leave it in neutral for a minute, it comes down to around 1800. If I turn off the engine and wait a few seconds, then restart, idle returns to normal. Motor is bone stock aside from headers and a KN, I haven't done any work to it recently other than an oil change. 186k miles. I'm thinking IAC going bad? Anything else that could cause this? Does anyone have a pic of the IAC location on the TB? Thanks for any help...
