Default Engine codes Party

Hi, my 2008 shake and stall when I start it during the day. I mean if it is full cold or full hot it's ok. 100k miles, throttle body cleaned, MAF cleaned, new fuel pump, new spark plugs, air filter replaced and a plenty of fuel treatments. Here the codes by memory
P013B, P0171, P0300, P0355, P0420, ( one more that I forgot it)
Any idea? Maybe exhaust manifold cracked? My gaz mileage is horrible.
thanks for answering.

I would start by clearing the codes and see which ones come back. By looking at the codes individually you have a bad pre-catalytic converter oxygen sensor, a bad catalytic converter, a bad coil and a vacuum leak or bad post-catalytic converter oxygen sensor. Not in order. All these codes together could indicate a bad PCM, wiring issue or corrosion in a relay or fuse box. Personally, I would start with changing the pre-cat oxygen sensor. Then check coils by measuring resistances. I make no guarantees and may be some others will respond with different ideas that will solve your problem.

Check for loose intake manifold bolts, common issue, causes leak downstream from the MAF and rough idle among many other symptoms.
