hanly2, I agree that replacing the Oxygen sensor should cure the acceleration stumbling. Get a crow's foot removal tool if you don't already have one. Need to remove the front passenger side carpet piece, unplug Oxygen sensor lead (likely a blue cable) and thread through driveshaft tunnel grommet. There should be Never Sieze on the threads of the new Oxygen sensor, if not apply a light coating before installing.
