I received the famous ENG PWR REDUCED on the DIC with a CEL. Mine happenend a day after the dealer replaced a fuel pressure sensor. hmm. Anyways I live a 25 mile hwy trip away full of high speeds and long hills. Anyone whom has had the reduced engine power knows that in certain conditions the lack of usuable power in somewhat unsafe so they agreed to tow. I confirmed with the service advisor that GM would cover and he said as long as its warrantied.

 

update. new high pressure fuel pump is being ordered.
