Too lean ... 200 1993

I have my check engine light on and I've been getting codes that say too lean/rich. I failed emissions the last time I went reading too lean (NOx). I've replaced vacuum hoses, cleaned throttle body, changed injector seals, changed air filter, cleaned and checked the bellows from the AMM up to the throttle body for leaks. I checked the throttle position switch.

After I cleaned the throttle body I checked the two vacuum inlets inlets just
before the throttle body (from the canister down by the left front wheel) and did not get much suction ... is that normal?

Also it will stall out when I first start it the morning and will stall agin when I first shift into gear. Also if I pump the brakes the idle will go erratic, stumbling ...


Any suggestions?
