There is no mass air on your truck,but does it sound like it's missing after it warms up. The TFI module could becausing your problem. AutoZone and some of the other parts stores should be able to check it out.

They've got the equipment to check the modules but you have to take it off and take it in.I tested a many of them when I worked for em. The test equipment should be located near the battery testers.
