I keep getting multiple random engine misfires that there seems to be no solution to fix the problem. The vehicle has been to the dealership several times. Runs for a while and starts acting up again. Stalls out when attempt to take off after coming to a stop or just starts to move and goes real slow, also has trouble getting up hills due to loss of power. Keep getting told it's catiloc converters and have replaced 3 times in last year. Have also replaced spark plugs and coil overs as well as fuel pump, mas airflow sensor, map sensor, oxygen sensors, and a few other things. Seems there is a lot of people with the same issues but no fix. . . .
