My recently purchased 1998 Civic LX 5-speed suddenly loses idle at a complete stop. Everything runs fine otherwise except in neutral at a light ect. It will stop completely unless I keep the RPM's up with the gas pedal. Is there a stepper motor or idle adjustment? Also I am new to Honda's, what is a good repair manual to help a shadetree mechanic work on their Honda (besides Haynes)? Thanks in advance for all opinions ect.
