Anyone get a code back from the scanner that reads EGR valve or EGR solenoid repair needed? I thought it was odd since my car does not have an EGR solenoid. I thought it might have been the gas cap, tightened it had the lady at the Advanced Auto Parts remove the code. Later on tonight, it came back on. Any ideas? Anyone have this before? Kinda new to the car (about 6 months or so) and it runs fine, now, but it still tripping a sensor somewhere.
