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.

Thank you very much I will try that this week
