Question about 2000 Daewoo Lanos
My friend bought this car in a emergency situation, and this is how she described it. She didn't notice if the car was idling fast when she bought it, but she did notice that it used a lot of gas. Wondering if it had bad leads to begin with and owner bumped up the idle to keep it running. Is there something else that might cause it to idle fast and use so much fuel.

SOURCE: running rough
If your car is running rough and it's fuel injected (which yours is). Follow the air intake (black plastic box - housing the air filter that has tubing that goes to the motor) until it reaches the Throttle body (rounded metal air intake at the end of the plastic tube - has one large flap inside). You will want to remove the hose clamp and thoroughly clean the throttle body and the AIC (air idle control valve - small canister attached to the throttle body). Use off-the-shelf cleaner from any automotive store. This takes about 30mins to 1hr depending on your skill level. This will result in a cleaner smother idle and smoother performance. This is a common issue in today's cars. I have to do this once a yr to keep my modified car running happy.
