The code says EGR Flow Insufficient. Can I just take the EGR off asnd clean it? Is there anything I can do without removing the EGR. My truck is seriously overdue for inspection, but this stupid county won't look at it if there is any code thrown.

Oh yeah. this is the 2006 Screw, 4.6ltr truck.

I hate this emission BS!

 

Check all your vacuum lines, PCV and hose for off or damage. Retest your code numbers. You should have more numbers. Is motor making a lot of noise or very low of power/misfires? Give us your exact code numbers.

 

You need a EGR valve. The DPFE sensor has gone bad and the only way to get it on your truck is to get a whole valve.
