CODE P1404

1996 Saturn SL1 • 158,000 miles

Exchanged, cleaned and finally replaced the EGR valve cleaned TB checked and no vac leaks reset MIL and P1404 returned after a couple of days driving on short trips. What additional things can I check to solve problem? Thanks

The replacement egr was bought at autozone part #EGR1044 both ports are clean and the egr was installed in correct position, could the evap system be causing CEL to keep coming back

A failure in the evap system won't set egr codes?How did you make sure the egr ports aren't clogged?

Cleaned ports by starting eng while egr was off car for a few seconds

That's a good way to see if the ports are clogged. But if they are clogged that won clean them When you did that did the engine race and you heard a loud exhaust leak? You don't want to over look that and waste a bunch of time looking at things that aren't the problem.
