I don't understand why the computer is worried about idle speed on decel but if i let off the gas at 70 MPH and let it coast I will get a code 35. Which means the idle speed is over or under by 200 rpm. I would assum it to be over becuase the tranny is still engage and the RPM is still 2000-2500.
does this indicate a vacume leak?
