Honda Accord 1995 Engine lights comes on and goes away when restarting the car

Hi,

My friend gave me  a Honda Accord LX 2.2 v4
1995. It sat for two years after I picked it up, I
brought it to the dealer and had him look at it, he
did all the necessary such as changing the oil and
all. He said that there was a ticking sound in the
engine when starting up. When it's warm the ticking
sound goes away.

The car runs great and haven't had any problems
with it.

But after driving for a week the engine light comes
on while driving. Not always tho, it has come on
twice in six 10 minutes rides now. But then when I
turn it off and I turn it back on the engine light is
gone... it also doesn't lose power or anything.

I was wondering if anyone experienced a similar
problem.

I'm driving this car in Wisconsin where it is 30
degrees Fahrenheit.

Thanks
