Anybody have a coolant tester?

[Solarsuplex]

Long story short, I've had misfires happening for a while now.

I got all new spark plugs. Swapped out all he coilpacks for working oem coils. I've done a compression test and each cylinder hit 155-160 so it's not the rings.

The last thing I can think of besides injectors would be a head gasket or cracked block. Wondering if anybody has a tester to see if there are exhaust fumes in my coolant. Or have any other ideas?

Thanks in advance guys.

Do a leak down test!

Just looked that up, was not sure what it was before. This would lead to more info about the possibility of my head gasket being broken. If anybody has a Leak Down Testing Tool that would also be appreciated. They are 39.99 at harbor freight right now..

Did you do a VCDS scan for codes ?

I have a scan tool, not vcds. But it doesn't show any codes once I clear the cel for misfire.
