Have you ran a compression test?

Yes, the driver's side was 125-135 psi and the passenger side was 90-110 psi. Although someone told me I have to have a battery charger hooked up. Reason being all the cranks drains my battery enough to give me false readings. Not sure how true that is but never retested it.
