I have a 1997 7.3 turbo power stroke.
my question is
Will unhooking the batery for several hous delete any code that may have been in the computer.
I have had some trouble with somthing and the check engine lite came on several times and I had am appointment for wed. to have a ford repair man to hook up his code reader.............Then I had started problems and had the battery unhooked for several hours.....now do I need to go on a trip and get the lite to come back on again before he looks for codes????
Thankyou for answering my question
