A sharp employee at Advance Auto when asked to read code took carb cleaner and sprayed around the passenger side of intake manifold. This caused the engine RPM's to increase. Remove the engine cover. A short vacuum rubber hose connection was replaced to fix the problem.

Car was missing terribly. Check engine light on. Poor gas mileage. Mechanic replaced the gasket connecting the plenum. He said these cars were common for this problem. He charged me $200.00 including the cost of the part which was $34.00. The first garage diagnosed that I needed the plenum replaced and wanted $750 -$800.00. Watch out for this and get a second opinion. I`m glad I did.

intake vacuum leak at the rubber boot connecting the plenum. Sprayed carb cleaner on it and engine revs up and runs smooth and I hear the vacuum noise of the spray being sucked in. One month ago heard a high pitched whistle when idling. Has since gone away.
