Idle problem
So out of nowhere my car is having an issue with the idle. It will idle normal(1000rpm) but then it will do this thing where the idle wont drop below 3000rpm. This just started last night and im not sure what to check. The car will idle normal then idle high then go back down to normal sometimes. What would cause this?

okay and heres why i cant figure this problem out...
i leave work tonight, start my car and rpms go to around 2,000rpm(normal on cold start) for a second and then go up to 3,000rpm again. so i drive not even a mile, and the idle goes to normal and the car is driving normal. car drove normal all the way from my work to my house which is about 10 miles.
i have no idea where to start looking for this problem at. and i have no idea why it just happens and fixes itself out of nowhere.
the car is on speed density so im not sure how a vaccum leak affects a car on SD. is it the same as a car running a MAF? im looking for any ideas on what to check since im completely stumped on this.

Talked to my tuner and he said if it was something in the map then it wouldnt of just started doing it out of nowhere. My car has been on speed density for months and had no issues at all. Like i said this problem just came out of nowhere and went away out of nowhere.
I drove to work today and the car ran normal. I am completely stumped on this

I had this same exact problem for 8 months and i couldnt figure it out. Then i called STM and they told me to check a hose on my egr. The hose pops off and causes it to idle bad and the idle to drop. I reach under and it was off. i zip tied it on and my idle is fixed and my check engine light is now off. Hope this helps

I had a prob a while back with one injector o-ring seal. Sometimes it misfired/caused idle issues and sometimes it didnt. It was a pain to track it down until a boost leak test.
Depends on the weather and how warm the car is. The rubber will expand or contract. Plus you mentioned that there was rtv around the throttle body. You could have a leak there. Good luck and keep us posted.
