Is this engine coolant on my spark plugs? P0300

Ever since refers to customers who come in for an oil change for example. Then, they say "Ever since you changed my oil my brakes are squeaking." They then proceed to demand a free brake job or whatever they come back complaining about. It's a term Technicians use to describe these type of people.

I wasn't saying you are that type of person just used the term.

I've been a professional technician for 8 years and it makes me laugh everytime someone plays this card.

Any luck with your Z?

Ohhhhhh I see haha so it’s more at jab at those types of people rather than Z1. Yeah I mean I have asked Z1 for their input but I live 5 hours from their shop so I don’t see myself taking it back to them.

It hasn’t thrown the code since I got it back together yesterday but the real test will be tomorrow morning.

When I started seeing that green stuff on the coils I thought surely I had a blown head gasket. So I’m just relieved it’s not that.
