Had slight bogging and twitching idle, then flooded and ECU spit out CEL with codes P0300, P0304, and P0003.

Clean filters, MAFS, throttle body. Reset EFI. What should be my next course of action? Sparkplugs?

You might wanna change your intake manifold gasket

Was able to convert P0304 to P0301 with trading of sparkplugs and coil packs.
Switched just coil packs back to original locations and codes went away but still bogs. Isolated problem to either coil pack or sparkplug; awaiting CEL to return to eliminate and narrow the problematic factor.

Isolated to Ignition Coil Pack.

$150 Denso replacement. Good as new!

i posted that then i deleted it. guess you saw it first. i thought about it and a leaky IM gasket will cause misfires but i highly doubt its the gasket.

Ambiguous. Wasn't a lie, but wasn't the best advice. Anyways, all cylinders are firing smoothly with good compression, so /thread.
