I have a 2008 ST 4.0 got the two lights today as I was getting on the highway and you could tell it wasn't running right but it did get up to speed but once into overdrive it would surge and it would not let you set the cruise. Turned around and took it home pulled codes and got P0401, P2135, P2111, P061B. its hard to believe that all these went bad at once is there one of these that could have caused the other codes because it was running bad? Yesterday I put a KN reusable filter in it and sprayed the air sensor with cleaner could this be causing a problem? all help greatly appreciated.:banana:
