Problem again?

[sonya1805]

Here we go again! 93, 3.1 grand prix about 5 months ago was chugging under load. Replaced egr valve, plugs, wires, fuel filter, hoses, oil sending unit etc. Ran great, now it's chugging again but this time worse, on idle too. Hooked up to computer & it's throwing code for egr again. I bought brand new one 5 months ago, can they go that quick or is there something other that could be leading to set the code for egr? SES light comes on after bout 10 minutes of run time, feels like maybe a miss, no smoke or smell of exhaust. Help please! Going crazy!

Did you make sure all connections to the EGR valve were clean when you replaced it? Try checking those. clean the 5 months old EGR valve, put it back in and see if it still happens.
