compression issue

2004 4runner V8 SR5.
I searched, with no luck...

Is there a light, or does the engine light come on when compression is bad, in 4th generations?

I have 87k

2 plugs on drivers side of engine read 80, one plug on passenger read 70, those were all the ones I tested.

Never tested before, and used a friends 20 dollar kit.

Runner runs fine really, no power loss etc.

What should I look for?
What am I doing wrong?

How could compression be bad with only 87k miles? If there is no light and the engine runs good then there's no problem.

Rule of thumb is to check you compression sensors after every headlight fluid change. Have you been doing that???
