Aren't you supposed to take out all plugs for accurate readings?

What do you pull?

J/K.

You can also check timing. Could be the cause of your problem.

You're supposed to push the gas pedal to WOT when cranking the car as well. Thats another reason for pulling the ECU or injector fuse, to keep the injectors from spraying fuel when you're pressing the gas during cranking. Try it again with WOT and you're readings should be higher.

doh.. I didn't even touch the gas while cranking, didn't think that would make a difference
Really appreciate all the help...

I was only looking a for a difference between the chambers...
