If I drive around for > 20 min and the turn the car off for 5 or 10. When I get back in, instead of idling smoothly around 1k it idles rough at 500-600....any ideas?

 

Mine does the same thing. I just haven't gotten around to sitting down and attempting to figure it out.

 

mine did the same thing and i had my toyota mechanic look at the problem he fixed it but ican't rember what it was ... anyway he is cheap and HONEST his number is 206 362-4821 located at 10729 auroura ave next to handy andy rentals ... i wo't be taking my rig anywhere else he makes his own hours ..

 

Have you cleaned out the throttle body? Mine was idling really strangely too, mostly too high because the butterfly valve was sticking. After I cleaned it it's been idling great.

 

1k idle seems a bit high,,,,,,,,,shouldnt it be more like 750 when up to operating temps?

 

i finnaly found the invoice my mechanic replaced the accelorator cable .. this is something you could probably due yourself ... i am not the best with mechanics althogh i'm learning .

 

Have you checked your TPS yet?
It maybe off a bit or bad.
