I own a 96 silverado 5.0 4x4 5 spd. when I'm going down the road and pull to a red light the truck will idle down but only to around 2k or so but after I come to the complete stop it'll go back to the normal Idle range. any Ideas what'd cause this and how can I fix it???

 

Hi!

This is only my suggestion, you bring your car to the nearest automotive shop in your place so that they can check the main problem of your car. I hope it helps. I also read some automotive topics like autopartswarehouse blog to get some tips and idea about car repairs.

 

sounds like a lazy idle motor...you may want to get it cleaned
