I have a 97 Honda Civic that my grandmother bought new, she passed about 3 yrs ago, my dad asked my to start driving it for him to keep it up. My wife takes it to work and back about 30 min drive each way. She noticed the other day after a long drive the rpms surged at a stop sign or red light. It does not do it on short trips, the car otherwise is perfect with only 30k miles. The rep at the honda shop said it was a idle air control valve, 250.00, before i replace this thing is there any other options? Is it cleanable, i have pulled it and checked it, and cleaned the exposed area, didnt seem to help. Any ideas?
