2009 vibe base model fwd 2.4 engine

[mv61]

i recently purchased a 2009 vibe base model fwd with about 120.000 miles, it ran great for about 2 weeks and the vsc light, came and check engine light, i scanned the codes and replace the upstream 02 sensor and maf sensor. I fired it up and drove into town about 25 miles and highway speed 65 mph. when I accelerated from the 1st stop light these and lights came back on, car runs fine and gas mileage has been good. The gas cap is tight and clicked and weather has been nice 70 75 above. i live northwest Minnesota. I have not unhooked the battery cables yet, but i have cleared the code on 4 separate times with a code scanner. The installation of the new sensors helped a lot.

Any information and thoughts would appreciated the code that comes is C1201, the lights coming on when to accelerate from a full or near full stop.

Thank you Mike in Minnesota
