I've got an '06 2500 Hemi 4x4.
Changed the plugs at 30k miles when I got it, with the factory Champions.
Out of no where, one day I started it up and she was hesitating/surging a bit under 2500 RPM while accelerating, but only for the first minute she was on.
I got codes 1128 and 1129. No matter how many times I clear them, they come back. 0132 was thrown today, but it did not come back.
I put a new MAP sensor on, and that did not change anything.
