So my civic idles at 1500rpms cold and went it warms it slowly raises to 2500 constant, doesn't mess with my driving or anything just my idle, I replaced the tps and calibrated it and now I'm at a standoff at what I'm supposed to do, there's also no vacuum leaks that I could find. I need some help what do you guys think it is,
1997 Honda Civic Cx Hatchback
Stock d16y7 except cold air and exhaust

 

You could try flushing out your IACV with carb cleaner and also clean its screen. Just unbolt the 2 - 12mm bolts leaving the coolant lines connected and go at it. If that makes no change you can also use the idle adjustment screw that is on the throttle body and slightly turn it in to lower the idle, do this when the engine is running and after it has warmed up. Set it to around 900rpm.

 

Imma try it tomorrow and ill let you know how it goes but thank you its very much appreciated

 

So I cleaned my iacv and entire throttle now it idles at 3k even when warm, and my idle adjustment screw is all the way in

 

do you have a vacuum leak? Check all your hoses to make sure they are plugged in and listen for any loud hissing noise under the hood
