98 f-150 4.2L low power and gas mileage
Someone please help if they can. I can tried going to ford but they want to charge me my arm and leg to find out what is wrong. If you are a a stop and try to go the truck seems like it has no power and good luck trying to get across a intersection. I have replaced the tps and plugs and wires and ford says it could possiably be a wire to my pcm andy suggestions would help

This is confusing, maybe when the moderator swings by he can combine these posts.
What size engine do you have? Does your truck idle poorly or stall at idle? Or do you just have a lack of accelerating power at low RPM's? As you apply throttle does the problem go away? Is your check engine light on?

Well, if it's idleing Ok, then it's probably not the IAC. Maybe the IAT like you mentioned in your other post. I don't have much experiance with the IAT so I'm not really sure what symptoms would show up if you had a bad one. I would imagine it would be something like you described.
Some one will be by eventually to offer some more info on the subject.

If you were standing toward the truck it was on the left toward the back of the air filter assembly area. I don't know if that helps. It didn't really idle better but if you put it in drive and pressed the gas (while holding the brake) it sounded better. The other thing is sometimes when you are driving and accelerating it will sound like it just sucked in a bunch of air kinda like a backfire in a way but not in the exhaust
