So I take it to autozone, brings up ineffient airflow...

1, we clean the 4 or 5 ports out, they were really nasty

2, we take off egr valve and spray carb cleaner/ leave over night and spray out in morning

3, put a new egr valve on and the damn light is still on even after I reset battery

What else do you guys recommand, im tired of this thing lol.. I cant pass the emissions test and im like a month late! (thanks for any help you can give)
