I have a 1991 Chevy s10 blazer. I was driving it up a hill, so I gave it gas. The car down shifted and revved up. At the top of the hill the when the car shifted back up, it stalled like it was out of gas, but it wasn't. Now the car will start but will not idle. You can rev it up by pressing the gas but it will stall out if you hold the pedal down. The only way to keep it running is to tap the pedal. The check engine light doesn't come on. When i unpluged the MAP sensor it the engine runs, but not as good as it should. I have cleaned the EGR valve, checked the PCV valve, changed the EGR solenoid, and the MAP sensor. I am out of ideas and could use some help.
