code 43...where's my esc?
I have been getting a code 43. I've searched the boards...TG ..TGO is back up and running!
I know it is either my knock sensor or my ESC module. I have a 91 z28 tpi with the 7730 ecm..speed density ecm. Where's my ESC module, my manual does not seem to have it in the book??
Please help! TYTYTYTY

Some have the Knock built into the mem-cal.
Knock sensor on the lower block.
Using a scan tool watch the knock counts and rap near the sensor and the knock should show up.
Or digital storage ocillyscope , Digital volt meter.
Don't guess! Test!
