Made it to work and put truck back to stock for the day...checked for codes and they were gone. Afterwork installed 87 perf again and it now revs great again and no DTC's present. Could someone shed some light on possibly what happened? This is the first prob i've ever had with it. i should have grabbed the codes a little better than what i did. thanx for any help....

I suspect this is a job for....The Mad Doctor! Whatever, at least the problem seemed to be the same for both sides of your engine! Sounds like it was "retarding" something - so this probably reduced the power.

Be interesting to see what the "Man", comes up with! (Glad I'm not him)
