Check your fuel pressure. For fuel injection, it should be 9-12 p.s.i. Your fuel pump is located in the tank. You might have to install an adapter fitting to hook up a pressure gauge. This can be installed inline at the throttle body or at the fuel filter. The fuel filter is mounted on the inside of the frame rail. You might just remove the fuel filter to see if you can blow through it. If you can't blow through it, it is plugged up and that may be your problem. You will need two wrench sizes to disconnect the filter 20mm and 16mm.

Monte carlo stalls


I would first try a new fuel filter.
Look at the spray pattern of the injector(s) when the engine is cranking. If it is a fine mist cone spray pattern, that is good. If it drips, doesn't really spray down and out, the injector may be clogged-or partly stuck open with trash or debris.
If filter is good and injector spray looks good, just possible an ignition problem-check the pick up coil inside the distributor. The PCM receives this information to determine the timing of the spark.

I have 1985 4.3 fuel injection Monte carlo that when driven for more than 20 to 30 min it will began to boog out or idle down so far that it will cut off and if u try to restart it, it wont start unle


Sound like a lack of fuel. Since you have replaced most of the ignition parts, I would look at the fuel system next.
Could be a clogged fuel filter, weak fuel pump, or pump relay.

Throttle body float stuck


They are pulling your leg

Only Carburators have Floats

A Throttle Body has Injectors

Could be an issue with the Mass Air Flow Sensor

Wrong reading on air flow you add too much fuel

2002 chevrolet monte carlo


My car was doing the same thing. It would stall out while idling or even turning a corner. I ended up replacing a few sensors but the problem was the fuel injector pressure regulator. The check engine light never came on. It was leaking fuel through the vacuum side of the diaphragm. Disconnect the vacuum hose from the pressure regulator and if there are any traces of gasoline it needs to be replaced.
