Engine Performance Help!!!!!!!!!!!!
Hi, I'm new, And have had my cobalt LS for about a year now, my car 2 days ago started jerking and surging and then ENG PER REDUCED showed on the DIC, and then my CEL came on. I took my car to autozone to get the codes read, it was P0101, P0068, P0842, and P0717. P0068 is throttle body airflow performance, and P0101 is mass air flow or volume problem. both my MAP & MAF sensors were replaced about 6 months ago along with my fuel cap, Im trying to figure this out as I need my car running again as its my only car. any one else ever have this problem?
