Fuel smell and idle speed

[ianmak]

Hi,

I have a 2001 1.0 Yaris. On a longish journey recently I recently experienced a pungent fuel smell in the cabin. It keeps happening but only after driving for 30-60 mins. Doesn't do it on short journeys. Maybe related is the low idle (under 1k) that rattles the whole car. Fuel problems happens with full and empty tank, so wondered if it could be mixture related, but hey I'm no expert. Only other thing is that I replaced the rad a few months ago and the problem started a few weeks after. Please help!
