I'm new here and female so don't know much about cars and need a little advice, I have a 2000 Uno 1100 Mia, Im told that the pcv valve could be a problem, does my car have a pcv and if so where is it and how much will the replacement part cost me
A PCV -it allows the crankcase to 'breathe' isn't expensive, though I don't think your car actually has one.. Hopefully somebody who knows for definite will read your post...
You don't mean a crankshaft sensor, do you?
Any half decent workshop would be able to help you
