Recently my car has been kind of stuttering on acceleration. It also kind of jolts back while driving at a constant speed. Anyone have any idea? I already tried unplugging the MAF sensor, didn't work. Changed the fuel filter, air filter, oil and oil filter, plugs and wires. I'm all out of ideas except maybe a few other sensors but I don't know which ones it could be.
EDIT: The catalytic convertor has recently been changed for being clogged so I don't think that's the problem
EDIT: I'm driving a 2002 Grand Prix GT
