    I had to pay for the intake gaskets to be changed - $239. Everything else under emissions warranty

    I noticed you had a incomplete combustion.... had a similiar problem...Starting using Premium gas for a month..then worked down to mid range fuel... all is still well. Put a can of Seafoam in at each fill up for a month. Also did CEL reset, which basically you unplug battery for 30 minutes...while unplugged hit your start toggle switch 3 times and that should clear out CES lite.

    Good Luck
