Well I got to looking at my gn today and the guy said there is a 30# chip in there. Well I look at the "green stripe" injectors and they have the #'s 03181AA and 621031 so they are 009's lol. So I took the chip out and it says on the sticker: DELCO CMW 0602. What chip is this? Thanks. BTW, you should see the spark plugs...they are blacker then hell lol!
