I have a 97 EK civic and it idle's almost at zero for awhile now I adjusted the idle couple times already and it STILL goes back almost to zero to idle. When its cold it idle's rough it feels like the car is gonna die out. E-mail me at j3poy209@aim.com if you can help out thanks..

 

Borrow a compression tester from a parts store and check your compression.

 

if you have a compression issue say in one cylinder and not the rest it would be well worth the money to get a cylinder leak down tester, if you have access to a air compressor that is

 

Also how many miles is on the motor? May just need a tune up. Fuel Pump, Fuel Filter, Injectors, Spark Plugs, Wires, Distributor, Rotor Button, the whole works. If you have done that get a timing gun on it, it may be a couple of teeth off on the timing. Go from there.
