-----------------------
Im wondering if my issuse with the ELC is causing my problem.
NO - while it might SLIGHTLY affect an accurate reading -
the problem is the OIL LEVEL SENSOR - it screws into the side of the oil pan -
you can check that the plug is clean and tight -
but it is probably defective - and needs to be replaced -
for a new delco switch -
the best price I found was $27 including shipping -
