Hey everyone, so I have a 2002 VW Golf SE 1.6. This is my first car and i’m learning in it at the moment. But after I get my provisional license I’m thinking of upgrading some things on it. Any suggestions on what I should do? Also my car has been randomly hunting revs after driving. It only happens when the A/C is turned off, when I turn it back on it stopped. Any idea what could be causing it?
