Ok this has bothered me ever since i bought my em2 and today i started to notice it as well with my teg. Usually when i step on the gas, the pedal is nice and hard to press its almost like u can feel the air rushing in or something(i know that sounds gay but its hard to describe..) Then there are other days where the gas pedal is soooo light to press and its almost like the response sucks *****.

Do you guys experience this too? What exactly is that, it seems to happen more during the day when its warm, but late at night if i drive its normal....

 

I had the same thing on my DA and all I did was tighten the throttle cable going to the throttle body. Its very simple to tighten.
But then again it could be a completely different problem then mine altogether..

 

its not that, ive tightened the throttle cable so there is no play, its more like some days the peddle feels lighter and no power and some days it feels stiffer and a lot more responsive...
