Will not idle. Sucking Air. Too Lean at Idle.
I have an 1984 Toyota pickup with the 22R. It's been sitting for a few years, but now I need to get it going.
If I put a sock, or like material over the throttle body opening the truck idles fine. As soon as I remove even just a corner of the sock (expose carb to air) it dies. I can keep it running without the sock if I push on the gas pedal to maintain a high idle. Of course at a cold start with the choke kicked in it will idle, but as soon as it warms enough for the choke to open it dies unless I push on the gas pedal.
I just finished rebuilding the carb, which made no difference. I also replaced a few vacuum lines. To check for leaks I held an unlit propane torch by different vacuum lines to see if the idle would go up, but it never did. I even tried plugging the egr hose.
Any help/leads would be greatly appreciated.

I didn't think that I typed 22re. It is a 22r. And it does have a carb.
I also forgot to mention. I used the old hose trick to check for vacuum leaks. i.e. you put one end of the hose to your ear and the other end you use to search for leaks. When you find the leak it will be quite loud. I haven't found any leaks.
