Re: [DML] Throttle sticking - I think

[jwit6@xxxx]

Sounds like the throttle valves are not closing fully, or the idle speed 
motor is passing too much air, or there's another intake tract point of 
entry. If you can push the throttle valves closed to the point where the idle 
returns to 900 rpm then its probably an issue with the valves or linkage 
binding due to grunge or wear. Once fully closed the idle motor should step 
in and regulate airflow to the intake side of the equation until a steady 750 
rpm is attained. If it never drops to 750, then its because there is too much 
air entering the intake tract. Your job should you choose to accept it is to 
figure out where it's getting in :-)
