i have a 1987 t4r with a 92 22RE engine in it.it has been running really rich lately and idk y i have done everything i can to it that i know and can afford..i changed the intake gaskets,thermostat,cap&rotor,new plugs,oil change...i have errors 5,6,7 (o2 sensor,maf sensor and tps i think) we put a new o ring on a leaky fuel injector and i ran b-12 cleaner through it...there is a torn air intake hose that is taped up no leak with tape...when in 3rd going 35 it will start jumping really bad...it smells so bad and im putting out a lot of black exhaust when i rev it even 20 min after its all warm...im on 31inchx12.5 inch tires and only getting 13 mpg its just eating gas...and last bit of info the intake manifolds were caked in black build up my buddy said unburnt fuel but idk.....please help i will try any thing i just want my baby running good again....thank you all so very much for reading and any replies

All of that makes me wonder about the wiring. Check your grounds and make sure they're solid.

22re ground wire locations - the guide!!! - YotaTech Forums

If you have a bad ground it could cause some of your issues. As for your intake hose, you explained it well. Replace the bad hoses. Clean your intake manifolds out, clean your throttle body, and check the specs on your afm and tps while you're at it.

From the sounds of it, that runner and motor has had a hard life and not been maintained well. It sounds like you have some catch up work to do. Clean the snot out of everything so you know that you have a good clean foundation to start working with. Check your timing, check the stats on your tps and afm. The tps and afm are some sumbiches on these things and can make your life hell when they're not working right.

Good luck and post back if you have more questions

Ya saturday me and my buddy cleaned out the manifold with carb cleaner and sea foam as good as we could we need a dunk thing to soak the parts in ...wats the afm...and how do you adjust a maf sensor and the tps or do they just get cleaned

You don't have a Mass Airflow Sensor. You have an Air Flow Meter, AFM. It's the flapper between your air filter and throttle body that senses how much air the intake is drawing.

So wats the best way to clean the afm ...and what else sgould I do.to get better mpg

Maybe your Cold Start injector isn't shutting down when the engine warms up.

I changed the o2 sensor It was caked in black stuff( unburned fuel?) And I sprayed carb/choke cleaner in the o2 sensor hole ...no check engine codes ...but when I do a quick rev it still puts out a lot of black exhaust...and smells bad ...I might take it to the shop they clean fuel injectors 25$ each ...any other ideas?

?

Its getting worse it backfired today and ideas?

Check your timing.

how dou check the afm

how dou check the afm

There's a step in the FSM that tells you how to do it. Just use a multimeter and you test the resistance between certain pins on the afm.
