Check air filter and clean throttle body with throttle body cleaner spray also replace fuel filter if have not done so in a while. Add some fuel injector cleaner to gas tank.

Firebird338 is blowing smoke. You don't have a maintenance problem and none of this junk will help either. (Looks like another know-nothing participant) Without laying hands on the truck myself, I would first want to know if the truck acts the same way after sitting and cold-soaking. I would check the fuel pressure (when it shows its symptoms of course). Check for codes. (You can also read the fuel pressure with a good scan tool). The other thing I would check is for major vacuum leaks. Hope this helps and don't follow junk advice - it needs to be diagnosed - as if throwing money at it could actually fix anything.

BTW - Ford Tech since 1985 Master ASE Tech since 1987 Master Ford Tech since 1998 I don't need to blow smoke

For some reason you obviously feel the need to be very insulting to someone who is only trying to help. OK, we're all impressed with your certifications. But don't look now, you're blowing smoke up your own tailpipe. Trying to impress yourself maybe?

Thanks OJ for that comment. They are just another cyber bully tooting there on horn. Glad I am a person that just lets in go into one ear and out the other.
