Jumpy idle

Post by Sql_RS4 » Wed Feb 03, 2010 5:17 pm

My idle got a bit rough and shaky, constantly changing between 740-800 rpm or 760-800 rpm I don't remember if it was 740 or 760.

Anyone experienced this?

Wonder what can be done and what causes this...

Thanks in advance.

Just put a rather low quality video of my idle, please see the shaky hand:

You could try to clean the throttle body, and then adapt with VCDS

OR maybe a air leak. Again go via measured block values on VCDS to check.

Right after my n249 delete (straight line to dv's), my jumpy idle was gone.
