Try unplug the trac switch and see if the problem still exist, it might just be the switch.

Swtich would not cause that problem.

Check your MAF sensor. Make sure it is clean. Wire cleaning agent may be needed if it got oiled by the filter.

I had Trac flashing and CEL not too long ago. It was due to MAF sensor not being installed properly.
