My wife's car has recently developed an annoying vibration. It is an intermittent issue, and when it does occur it is only under acceleration. If you lift your foot off the gas it goes away. As stated it is intermittent meaning it sometimes does it and sometimes drives fine, usually only occurs if you drive above forty five mph for a prolonged amount of time. One thing I have noticed is that if you turn hard at and cause the body to roll and put weight on either side of the car it goes away for a little while. We do not really have the extra money to have it diagnosed or to buy parts we do not need. Any idea what could be causing this? It started after a breather hose broke off the top of the engine (part of EVAP system I believe.

Is there a check engine light on and when it vibrates does it flash? If the answer is no then sounds like you bad drive axles. If the check engine light does blink on and off have it scanned for codes. Most auto parts stores will scan it for you for free. Keep us posted please.

The check engine light is on: P0411 (secondary air injection incorrect upstream flow detected). The light does not flash when the vibrations start. The vibrations started shortly after that code popped up. It is related to the hose on the top of the engine that blew apart. Also, the vibrations normally only occur after the engine has warmed up and been warmed up for a little while (six to ten minutes). I checked out the drive axles and they do not seem to be bad (no movement or wiggling).

I also have checked for movement of the engine mounts by having my wife rev the car up while I looked at the engine. Little movement as expected. I have also noticed that it will vibrate if the brakes are fully engaged and you perform a stall test like procedure by full gas and brake application at a stand still.

Hey EVILNINJA65,

I have to agree with JIS001 it sounds like bad drive axles, here is a video that will show you how to change them.
