While driving sometimes i feel a vibration in the gaspedal,then i step on the clutch to let the motor idle and the revs jump up and down between say 1300 and 1800rpm.
Now..if i tap the gaspedal it's gone and idle goes back to normal and the vibration is also gone then.
Also there's a weird sound that i can't really describe when this occurs.
Anybody have an idea what this could be?

Is it vibrating with the clutch in too?

check the throttle cable, might be too tight.

check to see if you have any cel's. you could have a small vacuum leak or a faulty iacv

uhm...why's this in hybrids? i'm boosted y0!
I be looking into vacuum lines though...thanks for the replies.

that forum isn't for people with boosted cars only. it's a forum for questions in the forced induction in general. your question is an engine/tech related. boosted or not, it has no affect on your idle.

also, please consider that every1 doesn't know your setup. you should have stated your EXACT setup when posting a question as such.
