First and foremost, "Happy New Year" everyone.
I have a 2001 Impala LS with a 3800. My issues is this. I initially cleaned my egr after getting the p1404 code, I then replaced the egr valve (AC Delco). Yet after a day or two the check engine light is back on with the p1404 code. I tried the reset I found online, by disconnecting the egr valve...erasing code...then reconnect, and the check engine light comes back (again). The car rides great and there are no emission issues.
Can anyone help or offer any suggestions?
