fisrt time user here. i need some help with my idle problem.i have a 02 tacoma 2.7l auto. every morning after my truck warms up ill be sitting at a stop light and the idle will go down to about 600 rpm after a few seconds of sitting, and the truck will shake alittle bit. ive had the plugs replaced ,throttle body serviced and fuel injection service done at the dealer. the truck mostly does this when its cooler outside. im hoping someone has had this problem before and can shed some light for me .any help will be greatly appreiated.

 

heres a for you

 

thanks for the help

 

I'm more along the lines of it's normal. Mine does it too although I have a standard tranny......it's a pretty big 4 cylinder so it's not going to be buttery smooth IMO....
