So I bought the 89 305 Camaro it was my project car stored away seem to be in running shape but it's running kind of rough now set for a lot of years previous owner ditched some project with this and I'm noticing missing parts they may be critical to the way it runs need help identifying what's going on here I think EGR setup must be missing there is a hose that comes off a canister that kind of blows out exhaust fumes and is a couple intake ports that are left open but they don't pull any vacuum I did a cigar vacuum test through the brake booster line there's nothing coming out of anywhere

Ok lol... So well if i dont plan on yanking it all off im guessing its emissions exhaust parts . That are not needed but will require new headers

If your wanting to eliminate the air pump. You can remove the check valves on the manifold tubes and install npt caps. I can’t recall the size 3/4 npt maybe .

So i can block off all the manifold holes and remove all that mess.. What do i do about rerouting the belt once the air pump is off

Will eliminating the pump and tubes require any tuning or cause a CEL or any issues?

Looks like the trans dipstick is a foreign occupier. The tube comes wayyyy too far forward. Probably has something to do with why the tube from the cat is shoved out of position. Assuming the pump is there, and isn't seized up, I'd probably just reconnect it.

The port under the throttlebody is part of the cooling circuit. Warm coolant comes out the lower intake, to the front of the TB, then out the side of the TB to the bypass valve. Looks like someone bypassed the TB. Common mod to keep intake air temps lower for performance. Also looks like the AC wiring is hanging out ziptied.
