Engine Performance problem
1994 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 160000 miles
For the past few weeks I have had a problem with this car idling at 1600 r.P.M.S It was annoying but drivable. I suspected MAFS sensor or air temp sensor. I cleaned them with carb cleaner spray and now the car will not idle below 2600 R.P.M. Before using the carb spray, I steam cleaned the engine as it was very dirty, then drove it 20 miles home with no problems. I have blown out all connections to sensors with compressed air in case there was water in them. Any ideas where to go from here?
