Revs. Too Low ?

[Toyota3000]

I just noticed that the revs have decreased, compared to a few weeks ago.

They were *that* low, that I thought the Yaris was going to stall.

What could have caused this ?

Is it normal ?

If not, is it a cheap fix to 'recover' the revs back to normal ?

Thanks guys :)

If its the same problem as me it was because of the weather, it was very low and only had 1 bar on the rev limiter. A long trip sorted mine out!

Happens to mine at idle aswell! There has been threads on this before and I think we discovered it was nothing to worry about!
