Re: glass pack question
Actually a friend of mine that used to have a 91 S10 with the 4.3L fuel injected, we took the cat, busted out the insides, and put it back on so it still looked like he had a cat on there, and a check engine light never came on as a result of that...
I haven't bypassed the air pump yet... I didn't want to mess with it at the time (all I did was unhooked the air tube from it so I figure it's drawing no power at all because it's not compressing any air, it flows in and flows out with no restrictions on it anyway, plugged the AIR manifold things in the exhaust tho) (however sometime this week I'll probably go back and remove that thing, and get the part number for the belt I use for it... )
