Idle up and down when in park & neutral
I have a 1988 325 i Conver, I cleaned the whole intake system, Verifed idle control valve, 20 ohms each 40 together. Cleaned out the Mass meter box, New air filter. Now thottle response is great, works fine in gear, Idle between 700-800. Now i have not checked the temp sensor due to I live in AZ and its always HOT. Can any help? Does the temp sensor (When broke) stay open or closed? Also... regardless of hot or cold it takes 15 seconds to start.
