P0355 - How To Replace Ignition Coil. '08 Rx350
I am getting P0355 error code and potential misfire codes on all cylinders. Engine light and VSC stays on now. Idle is unstable and power is a little jerky at times. I bought a Denso direct ignition coil to replace, however, Cyl 5 looks difficult to access. Can anyone recommend good non-dealer Lexus repair shop in Toronto Ontario area?

Sorry guys, I am a newbie at this. Further to my Dec 14 post: my 08 RX350 has 233000km (145m miles) and was running fine until a few weeks ago. In addition to P0355 error code, the code reader shows random misfires "P0300" on all cylinders P0301-P0306. Has anyone replaced the ignition coils on cyl 1,3, or 5? If yes, how difficult is it to access those back cylinders? Any hints or feedback on process and should I replace spark plugs at the same time

When I had them done at the dealer, they had to pull the intake manifold. So I had all 6 sparkplugs and the 3 rear coils replaced at the same time. That means new gaskets for the reinstall as well. I've done the front coils myself, obviously. But after spending an hour trying to figure out how to get at the back ones without taking the manifold off, I gave up and took it in.
Sorry that's not super helpful (or cheap), but if you do wind up having to replace anything on the backside of the engine, spend the extra coin and do them all.
