I have an 05 SE CC 4X4 and the truck is dying on acceleration. I have to be very very careful(slow) when I take off from a redlight or the truck will die. It's also backfiring and the RPM's are fluctuating back and forth when this is occurring or about to die. I then have to put the truck in neutral turn the key for SEVERAL seconds before it'll fire back up and then, once again, take off very, very slowly. The only 3 codes are: P0430, P1446 vent control valve (is this why my gas is spitting back out of the filler neck after every .90 cents or so worth of gas and takes forever to fill up!!!) And P0037 HO2S heated control circuit low, bank 1 sensor 2 thanks in advance guys I've had nothing but problems since I got this truck.

Got LED tail lamp bulbs? Take them out.

It sounds like you have some problems on the passenger side exhaust. Possibly a bad sensor if you're lucky. Swap driver/passenger side sensors to see if the problem moves to the other side. Or, just replace the sensors (~$75).

The vent control is often a blockage. Look this up on the forum. I believe there are few posts that show how to fix this yourself.

The spitting gas is because your purge valve is fouled. Search here for lots of posts on fixing it. And don't top-off your gas tank when you fill it...that can cause the problem.

I thought the heated O2 sensor was the air fuel ratio sensor & that's why it was dying? I also thought there was only one air/fuel ratio sensor so I wouldn't be able to swap sides
