Crown Victoria stumbling fix
My fix for a 2000 Crown Victoria had a stumbling feeling when I was lightly accelerating. The fix was simple! I took starter fluid that would clean and dry itself. I opened the top of the air cleaner box and sprayed the sensor until it seemed clean. The cars computer sensed the air mixture was incorrect at the most sensitive acceleration and fuel mix and has been perfect ever since. It lights up the tires from a stop. No stumble any more.
