    This would be more likely to cause a UIM explosion if the raw fuel were to get ignited in the manifold. I fixed the issue,, it was a short,, previous owner replaced the plugs and wires,, and a few weeks that's when I bought it,, then later on the metal on the o2 sensor got hot was shorting out on the rear drivers side plug wire, as they were touching. Had GM warranty the CAT, we are atand the warranty went to , no arguements from them on if it was covered or not. Add to your Watched Users. General Questions. Possible bad CAT converter.

    04 Grand Prix v6 Symptoms: 1/4th to 3/4 throttle and it bogs down on is between psi depending on idle or under acceleration.A vehicle that struggles or hesitates to accelerate may be unpredictable and moments of hesitation may be coupled with equally dangerous moments of surging or unexpected acceleration.

    An engine misfire can be caused by a few things. Most of the time it's going to be the spark plugs or coil packs that are the culprit. A misfire.Try cleaning the MAF.

    It can be frustrating for any driver to expect certain acceleration from their vehicle only to find that the vehicle seems to be hesitant while speeding up.

    Not enough air will throw off the air fuel ratio and make the Grand Prix jerk as well.

    It mixes air and fuel together and needs a strong ignition of the two to run properly.

    While ignition system is the most likely reason that a vehicle will jerk when accelerating, it is not the only one.
