Hey guys.. I have a little bad idle with my civic.. I felt it vibrates when it is on stops.. I felt vibration on the steering wheel And the idle is around 600 rpm.. My car is stock. No modes on it, changed air filter, and sparks plugs with a new ones. It has a Cel P0497... I also change the gas cap. Any idea of where I can star, can that CEL be the culprit of vibrate problems?

BUMP!

You need to take a vacuum gauge to the EVAP purge valve first. If it holds vacuum then one of the other valves is bad or there is a bad wire/connection. If it doesn't hold vacuum then the purge valve is bad.

Thx for replay..

Is the Evap purge valve on the throttle?

Whe u said the other valve were are those?

lazlong

Yes, it's on the throttlebody

There's a couple of valves around the gas tank

thx for the replay.. yesterday i was using Torque with an obd2 bluetooth scanner and i noticed that Evap Vapour pressure was giving negative numbers
moving around 13.2, -13.2, -26.3, -55.6 and even -110.. almost all the time stay in -13.2 or 13.2 are these value correct? or my pressure sensor is bad?

Check the passenger side engine mount, if the aluminum bracket is sitting down on the mount it's shot and needs replacing.

This is a example of a good mount, if those arrows were touching the mount needs replacement.
