R121 Resistor Mod

Has anyone else done the R121 resistor mod and had the solder pad pull away from the circuit board?

What is the r121 resistor mod ?

Got this from LS today.RW45 MISFIRE TECH BULLETIN.pdf (994.5 KB)

Aw, thanks for the info. I had the board out doing the l1 mod and wanted to make sure there wasn’t something else to do in there lok
