On my 02' d-max, while towing my 5th wheel the check engine light comes on, but only while under a load such as going up hill or starting from a dead stop. the code is the intake air sens. range performance and also the egr range performance.. but while driving without the trailer even under a load the light does not come on... I have a K&N fipk filter,5" exh. the banks big head and the six gun.. any help would be greatly accepted and retuned if possible
