I have a 1993 ford explorer 4.0 6cyl. 2 wheel drive. The problem i have is that it starts up fine and stays on while in park, but hesitates to rev up when i mash the gas, doesn't hesitate when i press it slowly, Then shuts off when i put it in gear at which point it takes a while for it to start back up. I have put in a new fuel filter and the gas pump is only a couple of months old. Sometimes it will let me drive for a little bit before losing power and act like i am flooding the engine when i try to give it gas, and it vibrates a little when i try to give it gas to try and speed back up to normal speed. Then i wait about five minutes and it starts back up like nothing was wrong. Been troubleshooting but can't seem to find what's wrong.
