Nothing to lose sleep over but another more common issue back in the day was the Primary TPS.
My first two went bad pretty quickly but the 3rd one is over 13 years old. I carry a spare just in case - <$150.
old TPS # T1245003
new TPS # T1245113
Symptoms are poor idle, stalling or surging.
Don't pull it but the inside of the PTPS sensor housing is either blue or black. Blue=GOOD T1245113!
My spare has external markings = "A28F0 A 2S11C"
Again, not a show stopper but some of us had Stepper Motors cause the same symptoms.
Easy replacement or some of us just disconnected it and manually set the idle.
For that price I wouldn't worry about these items.
