Check it.
Seriously, don't get in the habit of throwing new parts at it. That gets expensive. Most of your parts and pieces will last hundreds of thousands of miles and many years.
The solution is proper diagnosis. Then get a second opinion.
Example; my torque converter was unlocking and relocking while on cruise, causing a gentle surge. Three dealers and two transmission shops, including the largest, advised a new transmission. Amsoil analyzed the fluid, said there was nothing mechanicaly wrong. I drove it almost 100,000 miles before discovering my endearing problem was caused by a bad throttle position sending unit.
That transmission has only recently needed new solenoids, in 500,000 miles.
Saved money on that one.

Throw a scanner on it and check the engine temp
sensor reading and the IAC steps
These will cause a high idle you can remove the
IAC back of throttle body #20 or #25 torx
clean with carb cleaner and also the valve seat
in the body do not push pull or twist on the IAC
plunger
An air temp sensor will not cause a high idle
hell you can unplug the thing and it will still
idle right but it will trip a code
A vac leak will also cause a high idle check all
vac lines and the test port on drivers side
just below and back from the body in the side of
the manifold has a plug that likes to crack and
leak
The engine temp sensor is down by the gose neck
on the intake A/C side Alt side is gauge sender
temp sensor 2 wires
guage sender 1 wire
