I have a 1995 gs 300. The injectors sometimes will add to much fuel n cause the car to shut off n flood. I have to do a flood clear to get it started again. I have had two mechanics run diagnostics but it only gives codes for bad o2 sensors which is because of the extra fuel from jectors. What's causing the injectors too do this n it happen intermittently. 100700 miles.

SOURCE: o2 sensors

I don,t know how many there are. But they are ether in the exhaust manifold. or catalitic converter.

I had the same problem. I thought it might have been fuel lines clogged or fuel injectors. It ended up being a vacuum leak. My vacuum lines came unhooked and the main had a big crack in it. Repaired the crack and hooked the lines up and the problem went away.

could be clogged cats or may even be bad crank sensor.

SOURCE: 1995 ES 300 - antifreeze is draining from reserve.

Is the reserve tank cracked or have a deteriorated hose going to the radiator? Remove the tank to find out. A bad seal on the radiator cap can also lose fluid. A coolant leak anywhere can deplete the coolant level in the radiator and reserve tank. Check your owners manual for antifreeze type and mix ratio with water.

I know from experience that you should only use manufacturer recommended fluids in your transmission, Especially toyota, they are very peculiar about the fluids you use in them. Although the fluid you put in it may not cause any harm, it is always best to use the fluids recommended.
