The car would accelerate and then stall out. The motor would vibrate like it was jumping. Hard to start die after putting into drive. Had to replace the transmission and converter in 2011, spark plugs and wires have been changed. The car has blown sensors a month after getting it out of the shop. Have spent over 6000 dollars trying to keep the car running and the same thing keeps happening.
