PROBLEM anyone chime in and help me out
well i was driving and noticed my egrs were LOW, when i would let off the gas they would raise a little but driving they kept changing from 140 to 300s to 200s etc, checked the codes and got...
dtc code= po4od egr
temp sensor a circuit high
dtc code=p1000 obd system readness
what might these mean?......do i need a new sensor or do i need to reset my tune? and can i drive the truck without hurting it ....it just fell limp like slower then stock..and help would be appreciated..........
