Idling Vibrations

[frankl]

Hi how do you guys rate your engine vibrations when idling at the stop light?

Is it enough to bother you? i.e. vibration felt on the steering wheel/seats.

Or is it not supposed to idle at all? I just suddenly felt this may be an issue but i've only got 14,000 Kilometres on my 2005 Base Automatic. Hmm...

tire feathering could be causing the vibarations - new struts and shocks replacement can be the remedy. Recently I also noticed a shudder even I was just carefully travelling at 55mph, probably not the drivetrain but the engine that's causing it.

Thanks Chester but my idling issue is when I'm stopped, not while cruising

Have a peak at your engine mounts.

Their maybe all cracket up, or seized.

check your MAF - probably needs to be cleaned - I had the same problem - finally cleaned and the rough idle went away - car feels as smooth as when I 1st bought it.

what's MAF

[stevenspc]

MAF - Mass Air Flow Sensor. Here's a link to a PDF file that has a pretty good explanation of what it is and how it works. I've seen this type of issue before with other vehicles I've had and like the other post after cleaning the MAF the problem went away.

Hope this helps! Good Luck.

after cleaning the MAF you should feel a more responsive throttle & better gas mileage - not a lot but a little helps.
Hope this solves your idling problem @ the stop light.

question...been reading the link that steve posted but doesn't say how to clean the MAF. HOw do you clean the MAF for the 04' Matrix? I'm having the same problem too....

hey XR2003, thnxs dude...preciate the research you did for me, I will try it out tomorrow but I think i will buy the MAF cleaner @ auto zone, if there's any, if not, I will use the brake cleaner w/ spray...will keep you posted!

[XR2003]

ur welcome - a little warning though do not use the brake cleaner - may make the plastic parts brittle over time.
if there is no MAF cleaner @ autozone - use the electronic parts cleaner. same company crc - just make SURE that it does NOT leave any residue and that it is quick drying.
I learned this info. and more @ http://www.matrixowners.com/ - some of the people in here are long time members there.
please check it out & make some new friends.

dude, i just use the brake cleaner...aarrgghhhh! got too excited and didn't wait till tomorrow to clean it ! will it hurt if i only use it one time????

well, i did take it out and compare it to the picture (the wonder of wireless internet..hehehehe) and they are the same, dirty and after cleaning it, it was same color w/c is amber...test drove it and viola....idling is gone @ stop light and it doesn't get jumpy when i step on the gas pedal.....thank you XR2003, mucho apreciado

your welcome - one time use of the brake cleaner is fine - just make sure that after about $10k miles - when it is time to clean the MAF again - use the MAF cleaner or electronic parts cleaner.
