FORD F-150 FUEL PRESSURE PROBLEM

2004 Ford F-150 • 94,000 miles

I have a Ford F150 v6 4.2, while idiling or at a red light, it starts jerking like it wanna die out or it feels like its runnung out of gas but it has plenty of gas in it. I change the spark plugs and wires but it still does it. What could it be?

Scan for codes and check fuel pressure first, cleant throttle body with choke cleaner on both sides.

What was fuel pressure? If it's low you will get those codes.
