Misfire #6, #2, #5, #1

[Xcellr8]

Question, so I have an 03S that runs like crap. Barely drive able because of P0306, P0302, P0305, and P0301, all misfires in the cylinders represented by the last digit of the codes. IF an IMS bearing were in the process of failing, and the chain(s) jumped a tooth, could that cause these codes?

I've changed spark plugs and coils. No difference. Definitely a timing issue don't you think? Appreciate your comments.

Thanks,
Joe
