High Idle Gremlin on 5.0 L
Been hunting for high idle gremlin for a while; spent some time today checking all vacuum lines , especially on MAP sensor. Tightened all and got idle down a bit. Next check is TP sensor since it is throwing an out of range code.

Also check your idle air control motor. It will also give you a high idle problem.
