how come sometimes when im just driving around and come to a stop light or sign my civic will idle below 1000 rpm. then the car will just shake for a while and then it'll just shut off on me. what could be the problem?

 

idle below 1000 shouldnt be a problem. You could always adjust your idle to be higher but thats not gonna fix your problem, sound like something worse if it dies on ya.

List your engine and some more details if you can i'm sure someone will be able to help ya out here.

 

it's a b16a wit some bolt on parts.it's just a chipped ecu,aem cam gears,aem intake,dc sport headers.
