well I just finished a 700+ mile trip in the LTZ (3.8L) and the jerking/ chuggle/ fishbite, pain im my....is back
. The car did fine for the majority of the trip, but the last hour was horrible. I was lunging/ hesitating and the tach once again was jumping around a bit. I'm at my wits end with this!! Also noticed something else with this...the accelerator was harder to push and there seemed to be a lack of power as well. ARRRGH!! Does anyone have any idea what could be wrong and where I should start?? thanks
