Customer states that the car has a problem getting over 45 mph. At times. No check engine, but scanned pcm and tcm and found code p0703 stored in the tcm. Testing the brake light switch and it test fine. No problem with lights not working.

To be honest, I don't see how that code would relate to the problem you are having. Have you checked the catalytic converter to see if it possibly plugged? Have you checked fuel pump pressure?

I have not check much. I can not get problem to happen while I have it. Not really sure what to check. I did head gasket job 2 months ago and she said everything has been great til a week ago.
