Question about Toyota Matrix

1 Answer

Engine revs up down while in idle

2005 Toyota Matrix XRS Car continually revs and then low idles while in neutral. Also, when I'm shifting gears and I press the gas pedal it revs and accelerates very slowly. I have to let my foot off of the gas pedal to stop it from revving and then press it again.

If its been without the line for over a year, I Highly doubt it. Look into IAC valve. Most are installed with 2 screws, easy to adjust. Idle Air Control Valve. Look that up, for a start.

SOURCE: rough idle, backfire on acceleration

check everything you can under the hood your air intake system all of it especially make sure all clamps are tight .. and make sure all vacuum hoses are good and not cracking or broken or just loose . you might run a little fuel cleaner through a tank of gas too cleaning the engine fuel system up some. just a few ideas..

SOURCE: Engine runs rough after about ten minutes /idles really low

Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

Another place to look is your IAC, or Idle air control valve. It is bolted to the back of the intake manifold, and can be removed and cleaned. It is usually the cause of most Honda Idle problems.

Revs high when i change gear


Is it possible the clutch pedal is interfering with the throttle? Start the engine in neutral and allow it to idle. Press only the clutch pedal down and see if this increase the engine speed. If it does speed up the engine and slows back down when you release the clutch then somehow this operation is where your fault lies. If it doesn't alter the idle speed, then rev your engine and release the throttle to see if it returns to idle immediately. If it is slow to return to idle then your throttle cable could be sticking. This means when you change gear lifting off the throttle has little effect and depressing the clutch to change gear causes the engine to race as the throttle is still partially open.

Engine revs is too high when in neutral gear


First thing check for engine control module fault codes, if you have a lean running code then you have a vacuum leak on the engine, this allows air to bypass the idle speed control system and raises the idle up. Another issue is a sticking Idle speed control air bypass valve, but that is not common and vacuum leaks are.

My automatic Corolla AE110 vibrates when i stop in gear but it stops as soon as i start moving or when i put it in neutral.What can i do? Please help


It seems that your engine is tuned to very low idle revs, hitting the low resonant frequency of the car at tickover. When in neutral or revving up (moving), the engine stops shaking.
You can have it tuned to be slightly higher so it won't idle so bad, but you'll lose a little bit of fuel efficiency in the bargain.
Alternatively, just shift to neutral - free and easy.

This is very common on Matrix/Corollas and is repairable by way of replacement PCM to correct invalid parameters. the labor is low but the part is very expensive.

Expect approximately $89 or less in labor, and $648 for the new PCM
