Codes p301,p302

Intermittent codes, poor mileage highway 29mpg imperial at 60mph, coils, wires, plugs been replaced.
I am thinking battery or alternator may cause these issues. what do yal think

I would lean to the cheapest next and work my way towards the expensive stuff. A new battery sounds like it would not hurt. Do you notice any miss-fire or stuttering or odd downshifting when the codes come?

Wont start now.
Fuel pump was intermittent. Replaced pump and alternator. Battery tested ok
Codes for 1 and 2 cylinder misfire are still popping up. Reset them but still coming back as well as o2 sensor issue.

hummm...this is out of my wheelhouse now. I think connecting it to the computer at the dealer and doing some diagnostic might be in your near future. Hate to say that but I think that might be the next step.
