2003 Crown Vic Police Interceptor with 4.6 motor. The problem is the motor surges and bucks when it is fully warm, like its running out of gas or the ignition is being turned on and off. During this surging and bucking, once the motor is turned off if it, its nearly impossible to try and drive again until it fully cools down. It will start and kill start and kill and there is NEVER a check engine light. The light does work as I see it when I first turn on the key. The car runs good if its been cold and will go 30 miles without an issue, if I let it sit an hour or two and run more errands it may or may not happen. Sometimes its ok for a week. I have replaced the following in the last 2500 miles. Some items related, some just needed to be done. Intake manifold (was leaking antifreeze around stat) water pump and plugs were placed at the same time. New factory ford fuel pump, new fuel filter, new air filter, new throttle position sensor, and cleaned the MAP sensor with carb cleaner.
have the same problem?
