eastcabs Posted October 14, 2009 Share Posted October 14, 2009 My car started misfiring the other day while driving. It seemed to run fine up until this time. I took it in to see what was wrong and they told me that cylinder one had about 25psi and the rest about 175psi. Could it be anything other then bad piston/rings?
