Please do enlighten me then in your ultimately superior knowledge of compression pressure.

I have a theoretical four cylinder si engine that is now 24 years old has unknown mileage and has a miss-fire.
We have carried out a compression test and the results are as follows
Cyl1 -150psi, cyl 2 - 140psi, cyl 3 - 125psi, cyl 4 - 155psi.

You have carried out a wet test and only achieved a 5% variation.

So with your ultimate diagnostic capability you can interpret them result to tell me the internal engine problem yes?

I will await your superior knowledge over mine with your answer.
