I never heard of a check gauge light. I am going to guess you mean the CEL
. On my 99 the cel
does not go on when my gas tank is low. I wonder if there is a sporadic issue with your fuel pressure or the evap
system that is indirectly causing your cel
to go on. I would keep trying to pull codes. you know that a flashing cel
,means your cat is in danger from misfires.
I agree with the above check/clean iac
and all other sensors
