Hi guys. New to forum. I own a 2013 v6 Treg. We have owned since purchasing from local dealed for 3 weeks ago. 160k on the clock. Starts beautifully every morning approx 10deg cel in Australia. My wife takes kids to school does some shopping and parkes back in the garage at about 10am. Runs like a drea all day long.But.... Like clock work she starts the car at 5pm and it runs lime bucket of bolts. Stutters and seems like it runs on 5 cylinders for about a minute and then cleara out. Any ideas its driving me crazy.?
