Last weekend we had the oil changed in my Altima, the guys were ftiendly, informative and very professional. Today we didn't pass emission which I knew would be a problem but hoped the oil change would work for me. Not so much...We took the car back here to have diagnostics run, discovered we needed an EGR valve and the carbon blown out. Not sure if we were over charged, but the car us running better and we'll find out about emissions on Tuesday. I have no complaints, well maybe one...Don't give me grief about being a Bears fan!
