Hey guy and girls and others, I recently hit a problem with my H6 Outback 4GEN (2003 so it's OOLLLD) where I was driving it home, and about halfway I noticed it shuddering ever so slightly under load (sort of felt like a CV).
I noticed that as I pulled up to a set of lights it was still doing it, (even when in P or N).
Getting home I looked around for anything falling off, everything is in order, but it's still lollopy on idle like it's missing but no CEL light has come up, like it should for a missfire.
I was thinking that maybe it's got a bad head gasket (it's done 295k) but no exhaust gas bubbles are appearing in the system.
I was thinking that maybe a coil pack is failing but that would show up as a CEL fault, right?
I'm a little stumped!
Thoughts?
