Is this normal that my car takes a bit to go back down to idle. heres a vid. Do i need a tune the car? It does have some miles on seance Ive had it.

the 3.8l's are known for the idle decay rate to be high. You can alter this in the tune. You can try cleaning your MAF sensor and cleaning/replacing the IAC (idle bypass valve) on the upper intake (round cylinder shaped thing near the throttle body).

My old 01 did it~

Mine does the same thing. but I did notice that service engine soon light was on. Think maybe its time to do a tune up.

oh i know my check engine light is on. it says i have a bad egr valve or something. My last tune up was last month. I don't remember the code. i know its something about the egr system. I whent to the parts store and a new iac is like 80 bucks so i'm just going to clean it and see what happens. thnx guys.
