I'm having a crazy idle problem with my crx si. The idle is very high and constantly going up and down and staying between 2000 and 4000 rpm. I disconnected the battery and reconnected it a few times to reset the ecu but this problem will not go away. What is causing this????????

vac leaks, air in coolant, bad IACV
are the first things to check

is it throwing any codes? done anything recently to it?

It's not throwing any codes on the ecu. I saw a puddle of coolant underneath. This makes me think it could be air in the coolant. It's going to be hard to work on it today. This is what's going on here Picture 021.jpg

If you're leaking coolant, it's probably the problem. might have a bad water pump, hole in the rad or pipe/line, or popped the HG. check your oil to see if the later made it inside the oil...
