o2 sensor or intake gasket, if it's intake gaskets you'll notice it throwing lean codes and running big time rich. o2 sensor will do the same but its usually a lot more noticeable when its an intake gasket. So a little drop in your fuel mileage it o2, huge drop its gaskets
Yesterday when i had the truck in the shop it was throwing black LANGUAGE!!!!!! out the exaught pipes when i would rev it a little, but im not sure about the fuel mileage cause i changed the superchips selection from mileage save back to stock..
Intake gaskets. That things pig rich
I tried the brake cleaner around the intake and it didnt' make a bit of difference, could it still be the intake gasket?
you have a bad 02 sensor. replace both if you can afford to

Mine actually goes dead at idle, especially if coasting in neutral. It surges at idle, and has thrown the multiple misfire about 3 weeks ago. Gonna change 02 sensors and see what happens
its now showing code P0134 O2 sensor bank 1 not responding. which O2 sensor is bank 1????
I'm facing the same problem right now. I just replaced my plugs wires are on the way to me. Going to chang my fuel filter and get some injector cleaner and see what happens. I have spare coils packs so I just might change them as well and see what happens.
