I have a 1991 Toyota Cressida, straight 6, 110,000 miles. The engine idle will not come up to its proper 750RPM when engine is at operating temp. No Oxygen sensors have ever been changed. Which sensors could be causing the slow idle? I am selling this car and I want to make sure everything is in good working order before I sell to someone.
Thank You...

Is there good pressure on the clutch pedal? Miles on the clutch? This could be a throwout bearing and fork issue.
