Car has 106,500 miles V6 AWD, the day I purchase a new battery the RPM went to 400-600. We switched it back to the old battery and the same thing happen, car will turn off. I could not get a reading, it could not read any code. I though maybe it was a bad MAP sensor and so I bought a brand new MAP sensor but it made it worse. It won’t even stay on without having to throttle the gas pedal. I switch the MAP sensor back to the old one and the car stays on, but at 400-600. The second I turn on the AC, the idle drops to zero and car shuts off. The STOP ENGINE light will come on and at times it will say LOW OIL PRESSURE ( the gauge will drop) I checked the oil and its good. It was low so I added more. I checked if there was enough gas coming through from the bottom and reading were good. I read that maybe it could be a BAR sensor but I don’t see it on the car. I was told to replace the EGR valve, but can’t find it anywhere in the car ( where is it??) The car will start and run smoothly at 400-600 RPM but AC will cut it off. Please help. Tuco…summer is coming its going to b a hot one this year
