The speaker cover is part of the door panel. Removal of the door panel will be required.

Nissan Maxima

Multiple Codes

Car has 152,000 miles. Car idles and revs fine while in park. When driving it clatters and looses power it you give it more than 25% throttle. I took it to Firestone and they did a diagnostic on it and it gave them the following codes:P0420- CATALYST EFFICIENCY BELOW NORMAL (BANK 1)…..P1574-ASCD VEHICLE SPEED SENSOR MALFUNCTION….P0300-MULTIPLE MISFIRE DETECTED….P0720TCM REVOLUTION SENSOR CIRCUIT MALFUNCTION. The mechanic at Firestone said that he does not know why the car is acting like this and referred me to a Nissan dealer. I am trying to avoid that because I know the cost would be astronomical for them to diagnose and fix it. It was running fine and then all the sudden it was like it is possessed. Any ideas?


The code P0420 generally means the catalytic converter isn’t functioning as it should. Now if you have been driving it with a misfire for a while it may have caused a larger issue. The unburnt fuel gets shoved out into the catalytic converter and can cause it to clog. If the converter is clogged it will act as you described. A back pressure gauge is inserted in the front O2 Sensor port to check for this. If there is more than 3 psi at 1500 rpm the converter is clogged. Generally if this is the case the car will perform normal at first and as the engine warms up the performance will fade. I have provided the code information below.

Nissan Code P1574

Description: Automatic Speed Control Device Vehicle Speed Sensor

Code P1574 Probable Causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty

Nissan Code P0720

Description: Output Shaft Speed Sensor Circuit

Code P0720 Probable Causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. Transmission system malfunction

Nissan Code P0420

Description: Catalyst System Efficiency Below Threshold Bank 1

Code P0420 Probable Causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. HO2S sensor contamination/damaged
  7. Exhaust leaks or restrictions
  8. Catalytic converter damage
  9. Catalytic converter improper operation

Nissan Code P0300

Description: Random – Multiple Misfire Detected

Code P0300 Probable Causes

  1. Vacuum leaks, damaged hoses or improper routing
  2. Fuel contamination
  3. Ignition system – Ignition module, coil, spark plugs and wires
  4. Fuel system

2008 Ford Escape

08 escape when warm outside car shifts good but in winter when i first takeoff car hesitates for about 5 seconds before going into gear then is fine


First thing to check would be the transmission fluid level. Also check for any signs of a transmission fluid leak. Next checking for dirty fluid and finally checking and or replacing the solenoids in the transmissions valve body.

Oldsmobile Alero

There is a vacuum connector that pulls air in but whatever line connected to it broke off and disappeared. No one can tell me where it’s supposed to connect to. Autozone employees are all saying it’s definitely affecting the engine.  Here are the images:

Just a closer picture

Thanks. Driving us crazy.


Vacuum hose connector

It is my opinion that this hose goes to the MAP sensor. I am guessing the upper intake has been removed and when put back on the hoses were not set correctly. I am also going to guess if you extract the diagnostic trouble codes from the computer you will find a code indicating a MAP sensor issue. Use the diagram below to help assist in locating the MAP sensor. I think (3) is the end of the hose in the image you provided.

Chevy Suburban 2005

I am getting code P0306 NO. 6 Cylinder misfire. I have changed out the injector, coil, spark plug wire & spark plug. My car is still running rough and code still shows up. What is wrong?


Chevy Code P0306

Chevy Code P0306 means that the cylinder 6 is misfiring or is randomly misfiring. Start by checking for intake leaks and if no leaks are found the next step is to replace the spark plugs on cylinder 6.

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

Chevy Code P0306 Possible causes

  • Faulty spark plug 6
  • Clogged or faulty fuel injector 6
  • Faulty ignition coil 6
  • Fuel injector 6 harness is open or shorted
  • Fuel injector 6 circuit poor electrical connection
  • Ignition coil 6 harness is open or shorted
  • Ignition coil 6 circuit poor electrical connection
  • Insufficient cylinder 6 compression
  • Incorrect fuel pressure
  • Intake air leak

2006 Nissan Almera

Will not move

My car starts alright but will not move. The previous day my first and second gears took a long time to accelerate and there was a smell of something burning (clutch probably) after my drive.


Sounds about right. If the clutch is slipping or worn out the vehicle will not want to move. Something you can try. Hold the brake and let out on the clutch pedal. It the engine does not die, the clutch is shot.

1999 Opel Frontera

Loses power

Hello, what could be the cause when I start the engine and press on the throttle hard it withdraws or loses power and sometimes turns off. It only works when I press on the throttle very gently until it revs fully. It also withdraws when I engage the gear and start driving. I cant press on the throttle with force. My car has a manual transmission.


Lack of fuel would be my first thought. If the check engine light is on, extracting the diagnostic trouble codes would be the best first approach to this issue.

There may be a failing sensor or a vacuum leak involved and getting the codes would assist in pointing in the right direction. Just about any local auto parts store will pull the codes for free. Once you have the codes, post them below in the comments.
