   Autozone will do a free engine code check for you. Driving with the engine
light always on isn't a real great idea unless you know for sure what the
problem is and it isn't life threatening. For instance, my wife's '96 RAV4 had
the light on for awhile, but it was only giving the "fuel mix too rich" code,
which usually means (for that engine) the O2 sensor is bad, but I replaced them
and it would still come on, then I'd manually shut it off and it would go for
awhile before coming on again. I noticed that when it did come back on, it was
always after a fast highway run, then a quick slow down off the ramp with engine
braking. So finally I decided that it had to do with the fact that the engine
(at only 64K needed the valve guide seals replaced) was using oil again, and
*that* was the "rich mixture" problem, and was, in fact, only a momentary
problem -- but once the light comes on, it doesn't go off by itself, it has to
be turned off, at least in the Toyotoa gassers. 
   So anyway, I sure wouldn't just keep running with the check engine light on,
I'd really recommend to keep turning it off and trying really hard to find the
problem. What the code was the first time might not be the same the second
time. And if you don't have real guages, like temp, oil pressure, oil temp,
boost, etc., that's your only protection -- why ignore it?
