ford running compression wavefore
2012 e-450 6.8l came in for an intermittent mil. p0174 and
p0316 stored. -11% lt on bank 2 and +11 lt on bank 1. kinda
ruled out the usual suspects. but im pretty new to this
using a wps and fls very often and I was hoping to get some
other peoples input on the car. I did a relative compression
check and every other peak was about 1/3 small than the
last. I checked bank to bank cranking compression and there
was about a 30-35psi difference and running theres a bout a
10-15psi bank to bank difference. I don't really feel and
misfires and didn't see anything on mode6 but using a
cylinder balance test on the snap on it shows all of bank
one about -25rpm and all of bank 2 +25 rpm. none of the
cylinders show 0. thanks in advance
