my 01 v6 w/automatic tranny seems to stall when i drive a consistent speed for a few miles straight. When i say stall i mean to jerk or to not run smoothly. I have been told it could be the torque convereter, or fuel pump, or power train control module. I am up to date on my preventative maintenece. My guess is its the torque converter because sometimes when i let off the gas it jerks and when i come to a stop the rpms drop below 500 and my car almost dies. Anyone had the same problem or know what my problem is?
