    Apologies if I missed it but are you able to connect a scanner and check what if any codes it may be throwing up? You appear to have covered the obvious parts, I would've pegged it as a coil. It may be an issue with a failing signal line to a coil? I'd be checking for codes first before throwing any more money in parts at it.
