stock civic w/5 speed, 150k
Items recently replaced: alternator, battery

Problem: After the car has been running 5+ minutes, it will no longer idle when you come to a stop. It will idle but just barely and I'm having to give it gas to keep it going. Once I get going though it runs fine with no signs of any problems. Any ideas?

so the idle doesn't fluctuate at all? have you tried raising the idle a bit via the screw in the tb

skippysg

When it is warm, it stays about the same rpm and idling very rough or dying, not fluctuating. Tonight it died once on the way home but it starts right back up, popped the clutch as I was on a hill and it fired up.

I have listened for any vacuum leaks and nothing seems to be hissing, etc. I have never touched the screw in the tb.

and bleed the coolant system

Wouldnt air bubbles in the coolant cause the car to have a surging idle, not making the car bog out and die?

i did it to mine and worked like a charm....

I sprayed some carb cleaner in there for now until I have time to tear it apart and clean it. It has made a difference already. Thanks for the help everyone.

Clean the iacv and might as well flush the coolant in radiator.
