My GN lives and thank you to the forum

[Steve Wood]

I am with you on that one!

ESC Module is on back order at NAPA. Does anyone know where I might find one?

[Hill1430]

Also Steve, I have a friend with an 87 GN. I could test if mine is good or bad by plugging into his car. If mine is in fact bad, would plugging into his car hurt it at all?

[Steve Wood]

No...that might save you some money, or prove you need to speed it.

[Hill1430]

If his cat throws a code, will it clear when the hood esc is plugged in or does it store like newer cars?

[Steve Wood]

I would unplug the memory wire to clear everything and start fresh.  I would probably install his on your car and see what happens...stil l unplugging the memory wire before restarting the car

Might want to swap ecms as well if the esc does not work

[Hill1430]

Will do.

[Hill1430]

Update, I checked my esc on another car and it is fine. I removed the knock gauge and no more check engine light. Sending the gauge back to have it looked at. A big Thank You for your patience and help.

[Steve Wood]

Glad it turned out that way.  I was getting confused, but, at my age, I think that is my normal state.  It really helps to have another car near when you are troubleshootin g
