Vehicle engine stalls when in traffic. When I decelerate and engage the clutch (manual transmission), sometimes the engine speed will go so low, the engine stalls. It usually happens in very heavy traffic and I have to engage the clutch. This always happens when the vehicle is in motion. This happens pretty much anywhere, street, highway, freeway, drive way. It only happens when the clutch is engaged. If the car is in gear and the clutch is not engaged, it wont stall. I did take it to hemborg Ford in norco, CA and they reflashed the computer, but it still is happening. Yesterday 12 Aug, I was entering a roadway and a vehicle jumped in front of me. I applied both the brakes and clutch and when I tried to accelerate, the engine was stalled creating a very dangerous situation as I was already committed to entering the roadway and vehicles were approaching me from behind at a very high rate of speed.
