#1

3 and 5 low compression got spark engines runs rough engine light on.


#2

Compression measurement results on all cylinders? Diagnostic codes?


#3

After posting compression for all 6 cylinders, as per George, you might want to consider a valve lash adjustment

I’m almost certain this engine uses those bucket-type shims to adjust the valve lash

It’s quite possible the valve lash on multiple cylinders is too tight, causing low compression
