I just got done changing my ac clutch, pulley, and feild coil on my 2006 f150 with the 4.2 and the pulley spun freely and everything seemed fine when I put everything back together. I start the truck and it doesn't allow me to hit the gas and is idling low, kind of like limp home mode. Can anybody give me any ideas on what could be the problem? The wrench light and check engine light is on but I don't have a code reader. Any help is appreciated.

 

Buy a code reader. They can be found for as little as $20 online.

If the wrench light is on, you probably have a throttle body issue like I said in your other thread.

If you moved the throttle plate while the electrical connector was disconnected, you may have damaged it.

 

I don't know about the throttle body being damaged, after I changed the sensor the truck ran fine and the problem came after I changed the clutch, pulley, and coil

 

I guess you are going to have to read the codes.
