Throttle body screw

Band Wagon
I have the bone stock wagon motor on a 91 and I need to pass emissions but I'm at 431 and need to get to 220.
I was suggested to adjust a screw on the throttle body, that in the long run changes how much fuel the ECU tells it to send in but I don't know where the screw is.
Can anyone help by chance? Much appreciated.

what i would do---- warm up the motor pull the plugs and put a little seafoam down each cylinder let it sit for 10 min- "put new plugs in if orig ones are old" then run the car it willl smoke bad but clear up. then
Do the same with the brake booster line suck the seafoam up - about 1/3 can until the car stalls let it sit for 10 min then start it- that should clean alot of carbon build up on the intake and exhaust valves/ piston heads-
Put the rest of the can in your tank with 91 and run it for a while, about 1/4 tank- It has helped me many times.
195Kmi tacoma and the piston tops were spotless the shop who replaced the head gasket thought the botton end had been rebuilt- nope good old seafoam.
same with my Injector rebuilder- he thought i had replace the injectors because the flow was almost perfect at 195k miles he was impressed.
confirm your timing is set proper and the cap/rotor are clean- you should be good :encouragement:
if your motor has some miles on it its worth putting in a new o2 sensor- they are cheap.
good luck!
