I have seen many TB cleanigs on the site but noone has a Check engine light, or at least they didn't mention it. I check the EGR valve with a vacuum gun and it moves pretty good. If I disconnect the battery then its fine until you drive a while, 10-15 miles and then it comes on again and repeat. I have replaced some vacuum switches that seem to have low voltage etc... still no luck, I don't want to go broke fixing this thing and don't want to have to keep unpluging the battery. Any suggestions, Should I bite the bullet and put a new EGR in or what. Just a concern need some advice to get the wife off the back. thanks and God BLess
