my car idles really low... below 500 rpm's

i have cleaned throttle body and treated both tank and injectors and nothing has worked

i was told by a friend to "idle it up" ... what does this mean, would it help, and if so how do i do it

 

adjust the throttle cables maybe?????

 

check your battery and alternator and batteries Plus or somewhere, that could cause it.

 

adjust your idle air control valve or clean it

 

Does it idle smooth at 500? Mine gets rough when it dips to 600 every now and then..

 

you're lucky when i start the car it idles at 1500 then drops to a crappy 900rpm.

 

600 is avg for me after car is fully warmed up. Try the cables
