That truck was known for the spider injector under the intake. Not hard to replace. Upper Intake comes out as 1 assembly. You usually get a smell of rotten eggs when it fails. After replacement run SEAFOAM in gas ( and oil ) to clean out Carbon, fuel system and CAT

SOURCE: 1995 ranger 4 liter, rich on drivers side no codes, #6 injector faulty

Replace number 6 it is leaking.

If more than 75000 on all injectors, repalce them all as that is their normal service life/interval.

1995 Jeep Wrangler 2.5L HC & CO Emissions failed 2nd time. Replaced Catalytic Converter, Oxygen Sensor, Fuel Pump & Filter. It Passes everything else. I need advise please.

Failing HC and CO means the fuel mixture is too rich.
You may need a 4 gas analyzer to figure out why to know when it is fixed. Could be a leaking injector, restricted air intake, ignition problem, or a long list of other things. Even a faulty thermostat could cause it to run rich.

If the check engine light is on, you should have the computer scanned for trouble codes to find the area to test.
Could be a faulty O2 sensor, or leaking injector.

Runs rich very strong exhaust.replaced plugs 02 sensor. wondering if its the mass air flow sensor.

have you checked the air filter - a partially clogged air filter would make it run too rich. Also it's 15 year old car, check all the connectors and wires under the bonnet for security and cleanliness - dont suspect anything till you know the wiring is good.
Air flow sensor is highly likely - you're right to suspect it... but it could be a faulty temp sensor or even a faulty ECU.

1995 GMC Safari Loses Power when accelerating hard, rough idle

Do you have a check engine light on? Is this a 4.3 with central port injection? If it's running real rich it might have a fuel leak inside the intake, either a fuel pressure regulator leaking or a feed line to the injector.
