Question about 1998 Honda Civic
My 1998 honda civic has been revving like crazy when its idling. I read that trapped air in the cooling system could be causing this. So, how do i bleed the cooling system?
I believe the previous solution is confusing your AC system with your cooling system. Trapped air in the coolant is unlikely to occur anyway.
Check rubber hoses around the intake. Look for loose clamps or collapsed hoses that can leak air into the intake bypassing the throttle; a vacuum leak.
If OK, locate the engine temperature sensor for the engine control system. (Look in a parts catalog or service manual for the car). It may be defective. I'm assuming from your OP that the Engine light is not staying on. If it does stay on, there may be a trouble code saved in the engine control computer.

Sounds like your fan is not turning on, check that first. if there is air in your system you have a leak. you cant bleed the cooling system, you have to first recover the freon, preasurize it to see if you have a leak, if no leak vacuum the lines then add freon.
