found this:
at maxima.org. Is it a repost?
The only thing I could find from the ASIST is service bulletin NTB03-022 dated March 15,2003 for 2002-2003 Maxima and Altima: Hesitation on acceleration with Manual Transmission
Applied vehicles: 2002-2003 Maxima only with manual tranny and 2002-2003 Altima only with vq35 and manual tranny
Concern is for momentary hesitation when accelerating between 2000-3000 rpm
Bulletin applies only if your Maxima ECM part number is 23710-5y702 ('02) or 23710-6y300 ('03) and the ECM ID code is 030101 (these #'s can only be obtained with the consult-II (Maybe OBD?))
Note that early production '02s with ECM part number 23710-5y701 and 23710-5y700 with an ECM ID of 030101 will also need to replace the MAF (part number 22680-am600 which is the '03 Max MAF)
Sorry for the hasty post... trying to get this info and cram lunch at the same time. There is nothing in the bulletin as to exactly what the new programming does or what gets changed but at least its something.
Knowledge is power!
--- For our Altima brethren the application is as follows:
2002 ECM part number 23710-8j160 and 2003 ECM part number 23710-9j082 with ECM ID code of 030103 for 3.5L manual trans only
I don't have the capability to scan and post it but if someone can do that I can fax a copy to them.
