MVS Forum member HWG09 asks how to tell if his ’99 V70 R has a burnt valve, and what follows is literally pages of discussion on how to diagnose and treat burnt valve conditions.
Just in case I got a new coil in case #2 was bad. I put the new plugs in last night along with the coil and nothing changed. Still shaking.
Today I tried the new coil in every cylinder with no luck. So I’ve still got a shaking engine and CEL.

I don’t really want to take the car back in to the shop since I’ve pretty much done everything they were gonna do but I’m not sure what my next step is.
