Hello again:
Another quick question. The car runs and drives great but at times the idle "Hunts" up and down about 150 rpm.
It is the low pressure engine.
I would appreciate any suggestions as to the cause, and corrective action to resolve it.
The car just passed emissions.
Thanks, Ron

Try to have the throttle body cleaned first.

If not then the throttle body is bad and will need to be replaced.

THANKS FOR THE ADVICE. Is the housing the item directly attached to the rear of the air filter top cover or further down the line behind the engine. Also, any recommendation as to a cleaner?
Thank You, Ron Y

The throttle body is located under the intake manifold.

You car use Carb. cleaner or Brake cleaner to clean it.

The clamp on the throttle body hose at the throttle body is a little hard to get to. I always use a short 1/4 extension and a 7mm socket to get it loose.
