2 Codes P2096, P0313

My car is throwing these two codes. The P2096 i realise is the post cat O2 sensor on the bank 1 manifold which i will replace.

The P0313 is the missfire with low fuel level. What is causing this?

My search for the P0313 shows that people who throw this code usually are throwing a ton of other codes so i dont know if i have the same problem.

FYI, all this started happening after i replaced the intake boots.

Update:

changed the MAF, spark plugs, post cat O2 sensor on bank 1. Still getting 2 codes P0313 and P2096

Maybe clogged injectors on bank 1? I have used a couple cans of injector cleaner but no luck.

Thoughts?

P2096 or P2098 Post Catalyst Fuel Trim System Low Limit
P0313 Misfire Detected With Low Fuel Level

Do you have any other code from PEAKE tool? From the descriptions it seems you are having an issue with the fuel system delivery. Other cheap "normal" maint items you want to look at is changing the fuel filter, it maybe clogged or the pressure regulator in it maybe shot. Keep in mind when a sensor is telling you something that's bad, it doesn't mean the sensor is bad, usually means something else has gone wrong.

Just note that if all else failed, you probably want to get a mechanic check it out. Try not to replace costly items unless you know for sure it's the cause. (that MAF probably costs you some pretty pennies.).

Can you also post the condition of the car and also what mods / maint has been done on it?

I think you can get the fuel pressure checked. Before starting to replace the part. Let us know how it goes.

Check the fuel pressure and volume. Also do some testing just don't radonly replace aprts you have already spent more that it would have cost to have it diagnosed by a shop or DIY either way test then replace!!!

I had the same codes as the OP but I still can not seem to get rid of that blasted P2096 code. I replaced the water pump, thermostat and fuel filter and I cleaned the MAF and that got rid of P0313 (which I had twice...go figure) and P1619. My next step is to try and examine to see if I have an exhaust leak. If anyone has a possible fix for the P2096 then please post it.

Can a really bad valve cover gasket that's leaking cause the P2096?
