My cars been doing this for about 3 weeks now, even when warm and been drivin for a good 30 mins.

On idle it revs constantly up and down between 1k and 1.5k revs, up, down, up , down, up , down, sounds quite embarrasing when you stop at lights!

i can get it to stop if i position my foot on the throttle just right so it stays at a constant 1.25k rpm . at first i assumed mayb the very cold weather or something to do with the remap?

any help appreciated
 
yes exactly as vtec6000 says my brother had exactly the same problem on his crx vtec and was solved by flushing it out with break cleaner or obviously what ever it says in the read up :p
 
Also this seems to be a common Henry map trait, so may just have to live with it aha.
 
vaccuum pipes?


I thought i would post up what has seemed to be a fix for this problem, and it wasnt what i was expecting...

my battery was totaly out of juice at the time i was often needing a jump start untill i manged to find a battery with the right terminals.

since i fitted the new battery a week or so a go the car has idle'd perfect !


anyone ever heard of this?
 
Probably because the ecu would have reset when you removed battery to fit new one.
