cold start...........idles up and down
Hey i got a 93 civic coup ex with 190k miles. Its all stock and runs good. Only when I start it the rpm's jump from like .8k to like 2.5k untill it warms up. I cleaned this one thing in the back of the intake manifold and it helped but still does it now. When the car stands over a cold night, it is worse.
THANX
