98 tacoma v6 high idle problems

Hey, I'm new to this forum so bare with me please. I'm have an high idle on my 98 tacoma v6 at around 1700rpm. After a little research I changed the IAC valve, TPS, and also cleaned the throttle up and checked for vacuum leaks. After all of that still nothing. Any ideas or suggestions would be greatly appreciated. Thanks

 

I'm new, also. Just joined this morning. My 1999 Tacoma 3.4 Supercharged idles like yours. I asked the dealer to check on it and get it down to 750 RPM. At the end of the day, he said they couldn't and thought it was due to the supercharger installation. I'm thinking they haven't a clue to correcting the idle. Perhaps when I get a chance I'll attempt correcting the problem--wasting fuel.

 

After driving it a little while, I've noticed that it idles high but it don't do it all the time. You can kill it and crank it back up and it idles normal. I don't know what could be the problem.
