I know of no way to reset an injector. When they malfunction its often caused by contamination and or corrosion. Considering the labor involved in accessing them, replacement is the best option. I would try an aerosol based injector cleaner first, one that connects directly to the fuel rail.

Our mountaineer is getting gas into the oil. What could possibly be the problem.

Fuel pressure regulator. or stuck open injector/s. The only way gas can reach the oil is threw the piston rings. Gas will seep threw them. regulators can dump a lot of fuel threw the plenum. An open injector will bleed off pressure(when turned off)) and dump gas right into the piston.

Ok Darci this is Kyle Brazeal again I know it's not the O2 sensor I've already changed that so how can I tell which injector is stuck open and how do I fix it?

If an injector is stuck open, it would be hard to start, like in the morning. It looses fuel pressure. You can check the plugs for wetness and gas smell. This will help to isolate the injector. The only way to really check is to pull the fuel rail and leave the injectors on. Clean them and power up the fuel pump. clean them again and wait for the gas to seep out the injector/s. They should not seep or leak any fuel.

What makes the fuel to flood out into the air filter case

Could be the injector pintle is stuck open and just allowing the fuel pump to keep pumping the fuel in. Make sure you change the oil and oil filter.And clean up any gas before any further work. If you unplug the injector from the harness and just cycle the key no fuel should spray when pump runs. If it does than injector stuck open.

Gas injector spray gas all time cylinder 2 and 5 when you open ignition

92 kick. (there is no cylinder 5, sorry) it's a 4 banger. all are. that year.
must be the G16b engine. 16valve MPI engine, 1.6Liters.
open ignition?
on this car, the injectors fire about 3 to 5 milliseconds at idle.
3/1000'th of a second, only.
if they stick on, that is caused by the following
why not connect a NOID lamp to each feed wire to injector
and see what it is doing.??????
1: injector leaks.
2: fuel pressure way over 60psi and inject can hold it back.
3: ECU is stuck , bad injectors driver in ECU shorted.
in case 3 the noid lamp glows key on., steady.
4: the FSM stated injector balance test will fail.
5: the FSM stated injector leak down test fill fail.

these tests are the same for all MPI based engines.

connect noid,
key on,
the noid that glows, shows what ECU line is stuck low.
stuck low can be , bad wire or bad ECU, only.

if the noid test passes.
that is.
not stuck on
and as you crank the lamp flashes same on all 4 MPI harness connectors (injector feeds) then the electric side is good.
and the fuel side is bad.
if key on fuel pressure is near 30psi (see pump page same site)
then the injector is bad,

Fuel in #8 cylinder of 1994 351 windser-- enough to lock up engine

Are you sure that it is all fuel? If it really is then it has to be a stuck open injector. Unplug the injector to test if the problem is electrical or the actual injector (likely). If the engine is throttle body injected, no individual injectors per cylinder, then it is more than just fuel in cylinder #8.
