Question about 2000 Chevrolet Prizm

Acceleration problem on a 2000 chevy prizm. I have replaced the MAF sensor and installed new sparkplugs. Would an O2 sensor cause this problem? It idles ok, but when you hit the gas it chokes up

Change air filter and look for vacume line leaks

    Vacume lines are thin rubber hoses about 1/4 inch in diameter. There is always on that connects to the brake booster. That is a large roundish unit that your Master cylinder attatches to [where the brake fluid is]. Once you find the hose look for others like it and look for cracks or unconnected hoses. It is not uncommon to knock these off while doing stuff under the hood. Make sure everything is hooked up on the air filter assembly

The fuel pump is problematic its a "non serviceable unit" under the seat and under a panel with 8 screws it has an internal filter that gets plugged its a process to take apart and clean with a little rubbing alcohol and a couple shots of air from your comperssor if you have any questions just call me 702-469-9876 i can step you through it

Disconnect the fuel return line at the fuel rail and monitor your fuel pressure when the ignition switch is cycled to the run position several times WITHOUT starting the engine. Connect a hose to the rail to allow fuel to drain and not spray all over the back of the engine. If your fuel pressure is high (60psi or higher) it will show that you have a defective fuel pressure regulator , or debris in the fuel rail causing a blockage of fuel flow. If the pressure is normal with the return line disconnected it suggests the fuel return line is plugged up between the engine and tank or in the tank. Your issue is that you are Running extremely rich, hence your O2 reading .

2008 jetta will not start after putting new o2 sensors and maf sensor


Was the car starting before you installed the new components? if so reinstall the original MAF sensor and retry. May be a faulty MAF. The O2 sensors will not cause a no start condition, but the MAF will. Also be sure the connections between the MAF and intake are sealed, no other air can be allowed to get in between the MAF and intake.

Hello,
When the MAF on most vehicles reach a point of preventing the engine from starting, you can usually just unplug it and the engine will start. If that doesn't work-
You may want to try having the O2 sensor, ( Oxygen sensor ), checked. It works with other components of the emission system and can cause similar symptoms as the MAF, including preventing the engine from starting.

Trouble code p0134 and p0171


A code P0134 may mean that one or more of the following has happened:
  • Bad O2 (oxygen) sensor
  • Bad heater circuit in the O2 sensor
  • Wiring or connector to the sensor frayed / broken
  • Blown heater circuit fuse
  • Holes in the exhaust system
  • PCM failure
Possible Solutions The most common fix is to replace the oxygen sensor. But that doesn't rule out the possibility of:
  • Rusted exhaust pipe
  • Inspect wiring & connector(s) for problems
  • Excessive amperage blowing heater fuse (still requires replacement of sensor but also replacement of blown fuse)
  • Replace PCM (only as last resort after all other possibilities are covered.
A code P0171 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.
Possible Solutions Possible solutions include:
  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure

Most likely you need motor mounts for the shaking and clunking.
The check engine light being on could cause the accelerating problem. It could be something as simple as the fuel filter being old and plugged up. Have you ever changed the fuel filter? This could cause the engine to run lean making the check engine light come on. And when accelerating the engine will be "starving" for fuel causing poor acceleration.

Check Engine Light on 2000 Prizm


Most likely replacing the O2 sensor will fix this code, but that is not 100%, it could be other issues like a vacuum leak or a MAF sensor. The O2 is the one in front or on the engine side of the catalytic converter.
