You need to check the fuel pump pressure. Then check all the vacum lines around on the top of the engine. Also, check the air hose that connect from the air intake to the engine head. You may need to do the cleaning in the air intake malnifold. Open the rubber duck that connect to the air intake malnifold. You need to remove it completely. The rubber duck I clean it with soap and wipe it out with clean tower. The air intake, right at the throttle switch, I clean it with a bottle label, injection throttle cleaner. Do not buy the injection cleaner.
Spray it around inside the throttle intake and clean it. Do it at least 5 times, and clean it. I found there was a lot of dirt and crease stucked around the inside of the throttle switch. After I started the engine, it was shaking a bit and took less than a minute to start. But when it started, the problem seems never came back again.
I show this procedure to some people with the Explorer problem. They called me back and said they fixed the problem.
