it may be the multiplex unit. scan for codes and check fuel pressure, but things that are already messed up must be fixed first.

Sounds like the coolant temperature sensor could possibly be faulty.

There could be a clog in the fuel filter if applicable. The throttle position sensor may be bad. Before you look into these items get the fuel pressure checked. Advance Auto and Auto Zone both loan out test kits for this.

I replaced the throttle position sensor and now the truck the cl idles fine, but the service engine light is on. I had Auto Zone to test it and it gave PO122 Code .what can cause this after I replaced the sensor?

Our service manual is off line right now so I cannot look up the code. The fault codes should be cleared whenever you change out any sensors or electronics. Go back and ask them to clear the codes and see if it comes back. Also, get the code description just in case our manual is still down.
