Hi garyg369,

What was the trouble codes retrieved?

Did you clean the passage under the EGR valve?

Remove the EGR valve, spray some carb cleaner into the passage under the EGR valve and let it soak for a while. Use a stiff wire or something suitable used to poke the passage to dislodge the carbon and use compressd air to clear them. Repeat a few times if necessary.

Reinstall EGR valve and retest.
