not today but the other day.
Engine was hunting at idle suddenly last week. Got it to my Indy, diagnosed with a knackered PCV valve. Changed PCV and the car is happy and pulling like a train again.
Leading up to this, the car just didnt feel "right". It felt down a little on power and not as responsive.
Once the PCV was changed, it "feels" right again!
Repair was claimed under AA breakdown warranty.
