my car was doing some misfires on cylinder 2 and 4. it also had driver side wheel bearing bad, so i have changed driver side wheel bearing and since then i drove about 2000 miles and i didn't see my car misfiring anymore. so can bad wheel bearing cause misfire? i know they are two different things but saying? i have ordered 2 ignition coil, thinking should i return them or not.
Doubtful a bad wheel bearing can cause a misfire. I would return the ignition coils, and I would avoid installing non oem ignition coils even if they were to go bad. The oem stuff is bullet proof! They rarely ever go bad, but if you still doubt it, swap the plugs to the other heads. So if you get a check engine code for banks 1 and 3 then know that those coils are bad.
Did you ever wash your engine bay with water? Maybe you have condensation collected inside the plugs to the ignition coils. Or had your spark plugs replaced and the rubber seals inside the plugs didnt seat properly. Might want to check those, also if you noticed any wetness simply leave them unplugged for a few hours should dry them up nicely.

When you pull off the plug on the coil wire connector. Theres an o-ring seal inside each connector, make sure that is seated properly inside. If its not moisture gets collected and fouls the coil. I had this issue once and had a misfire

If you are on a budget pull plugs 2 and 4, clean up with sand paper and re-install. If not, just replace all of them and your good for a while. I get OEM's off amazon $40 a set of 6. Makes no sense to really replace only 2.
Our GS has a sensitive computer, if my car sits too long I can get a rough idle and misfire code when first starting. Just doing some freeway/spirited driving usually clears it up. Or change the plugs if its about time.
And I think its a good idea to replace both wheel bearings at the same time (driver and passenger).

We are not in the 70s, sandpaper should be nowhere near a spark plug. In fact, you're more likely to harm your engine with this kind of silliness than you are going to save money.
LOL! You wont harm your engine by cleaning up a spark plug, redo the gap and re-install. You are probably that guy that hires someone to change your tail light...
This is a totally acceptable way of cleaning of carbon build up to keep your car on the road. I think plugs are cheap and easy to replace, but a quick cleaning with some wd-40, sandpaper and metal brush is totally fine.
