Could someone please help my 2004 F-150 when I let off the gas to slow down it quiets it will not idle but it runs fine just won't idle when it gets warm it will idle when I first start it cold any help

 

Recommend you clean the throttle body and MAF sensor. Have you recently disconnected or replaced the battery?

 

Would love to help, but can't decipher that encryptor you're using to type. Not exactly sure what issue youre having exactly.

 

I disconnected the battery to clean the terminals why what does that mean

 

What your wanting to do is to remove the throttlebody from the truck, get some crc throttlebody cleaner and clean it really good. This is one of the easiest and cheapest things to do first.

There are several how to's on the forum that should help.

A dirty throttlebody can cause running issues such as you describe.

How long ago did you disconnect the battery?

There is a idle/fuel relearn process that the trucks computer will go through when this is done. There are steps to take that makes this relearn take place quickly but ultimately the truck should relearn on its own. May take 10+ or so miles.

 

They was another guy told me to buy a new throttle body position sensor said that was the problem what do you think trying not to buy a bunch of parts i don't need. I a m going to take tb off today and clean it to see if that helps keep your fingers crossed.
