When was last tune up? Plugs, wires, all filters & fluids??? Especially fuel filter??? I'd start there and run a good fuel system cleaner through it with next tankful of fuel. You might also consider having a fault scan done. (OBII scan) Autozone, Advance and any good parts store can do it for you FREE

My Chevy 2000 Impala chokes while driving?


If you mean acts like it's starving for fuel. You start by checking fuel pressure it should increase when you accelerate. If that checks ok then you need to check your mass air flow sensor.

White smoke and foam in the gas tank indicates antifreeze leaking into the engine somewhere. Do you smell antifreeze? You may have an engine seal leaking, most likely head gasket. It may be affecting the various engine sensors.

Where is bank 1 mass air flow sensor on 2000 cavalier


There is only one Mass Air Flow sensor .No such thing as a bank 1 or bank 2 Mass Air flow sensor on a 2000 Chevy Cavalier. I think you mean Bank 1 O2 sensor . For that I need to know if you have a 4 cylinder or a V-6 . If it is a 4 cylinder it is located in the center of the exhaust manifold at the front of the engine under the hood. If you have a V-6 it is still loctaed in the exhaust maniifold but at the end of it where the exhaust pipes bolt up

I have a 2000 Chevy Impala and my car only stay crank if my foot is on the gas, when I release , it shuts off. It's not the mass air flow sensor or fuel pump what can it be??


Inspect, clean or replace the Idle Air control valve...about $35 for the part...also how is the air filter? A clogged catalytic converter can cause this too? ( A free check at quality muffler shops. Hope this helps.

The knock sensor NEVER causes a drivability problem. DO NOT change it. Instead, clean the MAF, Mass Air Flow sesnor that's on the air intake tube near air cleaner. It is coated with varnish. Spray with carb cleaner several times and gently, gently brush the wires. Theya re glass coated. Be careful.

Then disconnect battery for 2 hours and then reconnect and drive for 0 miles for computer to relearn engine contrils.

Code reading


Hi. this code represents an issue within the mass air flow sensor. it is malfunctioning at this point. the mass air flow sensor Measures the volume and density of air entering the engine, so the electronic control module can determine how much fuel is needed to maintain the correct air to fuel mixture. There are two basic types: heated wire and heated film (grid); both work on the same principle.

A faulty MAF will cause driveability problems resulting from incorrect ignition timing and improper air/fuel ratios.

this device is located Under hood, center, upper engine area, mounted on rear of air intake duct


To replace a MAF sensor:
  • Locate the sensor.
  • Disconnect the negative battery cable.
  • Unplug the wiring harness and vacuum hose.
  • Unscrew the two screws holding the sensor in place.
  • Reverse the procedures to install a new sensor.
Please rate and god bless:)
