Is there only specific tools that can clear adaptation values on our ECU's or will a scan and clear at say Advance Auto Parts clear them? I've had my CEL cleared recently but I'm not sure if that also clears any adaptation values as well. I've been driving around with several driveability problems for almost two years and just recently got it all taken care of and now I'm experiencing a little flat spot around the 4 to 5k range and I'm wondering if it has anything to do with the ecu being adapted to all the problems my engine was dealing with previous to my repairs. I know it could be sooo many things but I'm wondering if it maybe something stupid like that. Thanks, Steve
