p1406 TSB 97 suburban

Does anyone have a copy of the TSB released by GM that covers a re-calabration of the EGR relating to a OBDII code 1406?

Both my suburban and a friends Cadilac recently gave this code.

MALFUNCTION INDICATOR LIGHT (MIL) ON, POOR DRIVEABILITY #76-65-04 - (Mar 3, 1997)
SUBJECT: MALFUNCTION INDICATOR LIGHT (MIL) ON, POOR DRIVEABILITY CONDITIONS (PERFORM FLASH CALIBRATION)

MODELS: 1996-97 CHEVROLET AND GMC LIGHT DUTY TRUCKS 1996-97 CHEVROLET TILTMASTER AND GMC FORWARD W4 MODELS 1996-97 OLDSMOBILE BRAVADA WITH 4.3L, 5.0L, 5.7L ENGINES (VINS X, W, M, R - RPOS LF6, L35, L30, L31)

Thanks GMMerlin... I wonder what the stealership would charge for this... (the last time I called the nearest GMC dealer they refused to perform the wiper circuit board recall replacement stating the recall had expired! LOL)

Luckilly the code has not reset so at this point I think I will just ignore it.

I have taken out the EGR and cleaned it but after awhile the P1406 code came back. What else can I do?
