I have a 2000 civic dx 70,000mi. no cel, starting is no problem, its only when i stop. the car idles erratic (does this all the time in the summer, and when its cold it does it less or not at all) sometimes it will go up and down for a long time, when this does happen it sputters on take off, and sometimes it just dies at a stop after struggling to stay idled

What i changed so far: plugs, plug wires, dizzy, fuel filter, both o2 and cleaned out my iac valve

I've been reading a lot of other forums about this same problem, but cant find a solution for this problem and im too broke to be fixing parts that are still good. Can someone help me with this one, Thanks!

Probably something going on with your injectors, clean em!

the injectors were replaced a year ago, so it cant be them...

There is a air mixture type screw on your throttle body that you can adjust that should take care of your problem. Just be sure to only adjust it when the car is completely warmed up. You want to loosen the screw so that the idle adjusts up.
