Fiesta 1999 - hesitant acceleration during misty / foggy / damp weather? - clappedout

I've recently noticed that when the weather's quite foggy / misty / damp, the car can feel very hesitant in acceleration.

I think it mostly happens in 2nd / 3rd gears, when it just feels flat and could potentially stall when in first.

What could be causing this and what would need replacing?

When I do get going and try to apply some gas, you could hear tickety clicks and maybe some slight whistling (I think coming from the exhaust system).

Thanks
