1999 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 114K miles
The Service Engine Soon light came on and I had it checked. The code came up that I needed a new oxygen sensor. We replaced that on 02.12.10. Drove it for approx. 45 miles and on 02.14.10 the service light came on again. When checked this code showed an EGR valve problem. After doing some reading on your site it seems like the first option would be to check this for carbon build up and try cleaning it before replacing the valve. Any other suggestions for troubleshooting before going to replacement. And what are other related codes that might come up?
have the same problem?
