I recently bought an '84 Camaro with an L69. The smog pump had been disconnected, but was still in the car. The vaccum lines were very messed up and the egr valve is shot. I decided to take it all out since there aren't emissions test here and it was very difficult to fix a very small coolant leak that I had.

I ran new vaccum lines as I understood should be done...........Here's what I did........
There are 3 tubes coming from the exhaust manifold, one on the driver's side and two on the passenger's. I ran a hose across the engine to connect 2 of them, and pinched a hose off on the third.

The ECE valve is shot, so I just left bare, no hoses or anything. That's what I think it's called, the one that has 2 connections and is coming out of the intake manifold, near the thermostat house, but not one of the two on the housing itself. The air canister then had a hose to be pinched off, two of them actually, so I did.

The pvc valve has a hose running from it to the carb, like the emissions diagram shows. The air filter canister is hooked up just like before......

There is one more vaccum line coming off of the carb, and that one I just pinched off as well. When I left that one open the RPM's stayed at 1500 at idle.

Now here's the problem.....

The electric choke stays on............

There is a slight hesitation when I floor it in idle and the hesitation is at about 1500 rpm.

Car still seems to have plenty of power, but not quite right..........I think.......

So do I have to hook everything back up, which was done very poorly in the first place, or is there something that I missed?

 

Your car is fine. All that stuff is just emissions crap that ur engine doesnt really need.

The condition you described is the engine bogging, from your Quadrajet. Does that on my car too... Just get used to it unless you wanna get a new Holley or Edelbrock.

It isn't bogging, it is a hesitation, and it didn't occur before. Now I've disconnected one of the electrical controllers, and it's solved. My idle wants to be at 1000 even after I adjusted it last night.
