2001 Camry LE

I have a 2001 Camry LE with a 2.2 5sfe. It started missing bad a few weeks ago. It has PO300, PO303 and P1310 codes. We have replaced spark plugs, spark plug wires and coil packs and it still runs like crap. Missing, cutting out, not taking gas when you start off from a dead stop, and cutting out when you go up a hill and have to accelerate. Anyone have any ideas? Thank you very much!!

I realize you posted this a while ago. Sadly this forum isn't what it used to be with help. Two of those codes seem to be a misfire on cylinder 3. Try pulling the wire to confirm you have spark on cylinder 3. If you do try doing a compression test on all of your cylinders.
