92 Civic idle speed variation
My daughters '92 Honda Civic idle varies from day to day. She says it often seems the vary with the air temperature. I have from time to time adjusted the idle up or down a little.
I understand that leaks in the vacuum hoses can affect idle speed as well as a number of sensors. Visually the small vacuum hoses look OK.
Anything I can check out myself realizing I have no particular skill or special tools? It seems to idle faster on warmer days and vice versa.
