Guys,

Recently did over the bottom end of my 5E.

Did a dry compression test and got these results

Cylinder 1 - 180
Cylinder 2 - 170
Cylinder 3 - 140
Cylinder 4 - 170

Car started misfiring this afternoon so trying to get to the cause of the problem.

Help?!

That difference in pressure might highlight a problem, they should normally be within 15-20% of each other for a healthy engine.
