EGR Flow Insufficient (1 Viewer)

[steverino]

Replaced my 02 sensors and am now getting the EGR flow insufficient code.

Any reason this would happen right after the new 02's?

Probably coincidence. Reset the ECU and wait for another failure, then start troubleshooting this well documented issue.

sounds familiar, I had a 420, replaced cats and O2 sensors, then got a 401, replaced vsv, then got a 402. WTH? The following link fixed it and i have been code free for 4 months:
