Code P0420????
Hello,
This is my first post to this forum, and I am doing to for a friend. Lately, her civic's (1997 LX) engine has been surging at idle speeds. It goes from about 800 to 2000 rpm when she is in neutral (manual tranny). But there is no ill effects when she is using the accelerator in regular driving.
She took it to Autozone and they told her that the ECU was showing a code of P0240. Can anyone tell me what that code means?
Based on what I know from other cars, it sounds like a vacum hose might be bad. Are there any hoses that are praticularly proned to breaking? Or is there a component/sensor that is known for going out?
