Idles up n down n park n in drive when I come to a stop

[Daddyydex]

Hey guys I have a 95 civic with over 300030 miles on it. It's drives smoothed no check engine light. My problem is when I start the car n after a little while before it warms up it idles up n down ok car warms up it still does it. So now I'm n drive n I'm driving n when I come to a stop it idles but makes the car pull forwards constantly what can be the problem? I tried bleeding the cooling system many times even draining all the anti freeze out n puttn a new batch in. Please help

You said it drives smooth but also surges while cruising? Can you re-state some of that in more organized, shortened sentences? Its hard to understand exactly whats going on.

Automatic I assume? Auto's always pull when stopped and have a gear selected. You just notice it more when you're idle is higher. In my last auto, for the winter, I cranked back the throttle cable so it would idle higher and stay warm in the negative temps. Though at a stop light, i had to hold the brake a tiny bit heavier cause the car wanted to pull a bit more.

Have you done anything with the IACV? If not, google it. It will also cause crazy idle issues if it's dirty. You're right about the coolant also causing it. Are you positive coolant is circulating through the whole system? You have heat correct?

No it doesn't surge while driving it does that everytime I stopped at a light and when I start car to warm it up before it even gets warms and the line is still at the C "cold" is idles up and down. Umm I haven't checked that iacv but I will google it and see

IACV sounds right on the money. Have had that happen to me 2 different times. simple change (or careful cleaning) is likely gonna fix it

civics also surge when they have a vacuum leak

^ this
start with the IACV either clean it or replace it
if that dosent fix it then start looking for vacuum leaks
the tps can also cause such problems, but the other things are more likley. So start with the first two and if neither one of those work come back and see us
