P0401 - Exhaust Gas Recirculation Flow Insufficient Detected
Anybody have experience with this code? I've thrown it 4 times in the past couple of days and a few times last summer. It also throws a P1000, but that would be expected due to a failure on emissions testing.
So, I'm thinking that maybe soot has clogged the return to the air intake? Anybody have some input?
