CEL after battery disconnect

[aussieboxy]

I disconnected my battery to fix the dreaded horn problem with the grommets in the steering wheel. Only had it disconnected for a few hours.

After reconnecting the car ran really rough & has come up with a CEL.

Any idea's?

Disconnecting the battery should not throw a code, but considering that you were working on the car, I'd get the code(s) scanned and let us know what they are..............

I disconnected the battery for about 10 mins then reconnected, CEL disspeared.

Go figure.

How's it run now?

Go figure.

And in doing so, lost any chance of finding out what the problem was...........
