[QUOTE="Artisanau, post: 459761, member: 19863"] Hi Selenarainie, I thought I’d seen your post over the weekend. So you did a vacuum leak test. I assume no leaks, ‘cos you didn’t elaborate. Still got a P300 showing? The best addition to my tool kit was a leak down tester for my misfire issue. I was convinced it was everything else because it ran so well until I got a misfire at idle in traffic conditions. The leak test identified poor cylinder compression which ultimately lead to an instant repair, but it had me fooled. Keep your post/thread going, it’s interesting and you’ll get a fix. 👊 [/QUOTE]
