hi everyone. i am new for this forum. Last week when I drove home my luxes acting weird that when I drove slow shift >40 the engin acting shake and stop in stop light. This is the first time i seen. Then The TRAC OFF light flashing along with check engin light. I went Autozoon and I got this code p1349. I change the spuk plug and oil control valve filter. then the Trac off light disappeared for two days and come back again along with check engin light. Today I got three code P0171, P0174, and P1349. Is anybody has those experience? the car has 150k mile
