Havent driven my car for a whole day during the rain yesterday, and this morning I drove it. I realised the pedal (accelerator) is very hard to press on.

Very hard to explain.

But when I reverse slowly, seems something is blocking it, or very sticky. So I push harder and it would rev to 2-3rpm.

Pedal is fine after normal driving, just when I stop and accelerate the pedal seems very hard to push in.

Sorry cant explain clearly, it's so freaken hard to drive too
