EGR Valve Position does not match desired, limits based on engine speed/load.


It appears your EGR valve is sticking, the EGR valve position sensor is bad or the EP sensor is bad.

A/M air filters tend to make FMC & dealers void your engine warranty. The K&N system is probably the worst A/M air filter you could have chosen for the 6.0.
What type of air intake would you recommend for the 6.0. And, what is the problem with the K&N system?
