Recently started getting P0406. Did the typical EGR unplug and reset procedure, which usually gets rid of it, but it keeps coming back. Likely carboned up this time.
Around the same time I noticed a weird hesitation only at a certain pedal location. Feels like a heavy misfire. Seems to happen regardless of transmission gear when I just barely push the pedal to keep moving. Below and above this spot on the pedal everything is fine.
Going to get my scan tool and investigate further when I have a chance. Could the EGR issue cause this? TPS? IAC?
Edit: Updated to proper code.
