I have a 1983 ltd Crown Victoria with a 5.0 engine. I have taken it to 3 shops and they r stomped. I starts up, runs and shuts down. When u start it up it runs but when u put it in drive or reverse, it shuts down. I replaced the throttle body, I replaced the torque converter. It still starts and then put in gear it shuts down again. If I hold the break and gas and put it in gear it will go. I can run it down the street with out the break, it will run regular till I need to come to a light and slow down it shuts down. Its got good fuel presure. I had the checked. Please help if u can.
