Ok, how do I do the leak down test?
I have swapped the coils out with an older set that I had and tested all of them again. All are firing with both sets of coils.
Old plugs looked all looked similar, kind of hard to tell bc when I pulled them they got covered in oil from what was left in the plug wells but nothing appeared to be wrong with any of them.
Tried to do a compression test, but my battery died so Im charging it to try it again, but what I was able to test was Cylinder 1-125#, Cylinder 2-108#, didnt get a chance to test Cylinder 3, Cylinder 4 didnt register any compression (tried it twice). Will try again once battery is charged, but its looking like it dropped #4. Strange is its not making any abnormal noise other than the misfire.
