Hi, I have an old 1991 Hyundai Excel. The engine light came on during
the last 1/2 mile on my way home last night. What engine parts could be
screwed up? Would the light be telling me I have a problem with low oil
or low water or would that have it's own designated light icon?
Could be a lot of things. Did you just get gas? If so, the gas cap may be
loose and that can give a signal. If that is the culprit, it will take
about 15 or 20 starts to go away after tightening the cap.
Oxygen sensors go bad also. Very common cause. To know for sure, you have
to use a computer for readout of hte information. The car is still drivable
as is, but there may be long term effects if you don't get it check out soon
to know for sure what the problem is.
