ck eng light and wrench help

[Jim Barnett]

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:

Ive heard about mechanics complaining about oil from intake filters gooing up sensors. A light mist is enough if you did install an oiled filter. Probably some good vids on you tube about spraying a light mist on filters. Hope its an easy repair once you determine what the cause is. :driving:

My guess is the K&N was over oiled. Happened to me once on the "stang. Get the right type of cleaner and spray the sensors. Then try a regular filter. If that works. Clean the K&N with soap and water let it dry and reoil very, very light lightly.
