"Check Engine" light normal after Cam install?

Just got my cam install done. Car drives fine, I have unhooked the battery and re-hooked it back up. Still a light.

List of work done.

-Heads taken off, "decked" (or made flat), intake ports "cleaned", exhaust ports opened up quite a bit.
-New 224/224 .563 112LSA TR Cam/springs/pushrods.
-New Underdrive Crank Pulley with new belts.
-Exhaust system was taken off and then put back on.

I am going for a re-dyno tune shortly (already have a LS1 Edit tune on). Will this fix things up?

Thx for any insight.

Its normal. I had the SES light on when I did my TR224 even though it ran it didn't run very well. A tune will fix ya right up.

Whats the code??? It might be something as simple as you damaged an O2 sensor when you removed the exhaust. If a sensor is bad a tune will do nothing to help ya.

You probably have a P300 (random misfire)

The lope at idle and subsequent rapid short changes in crankshaft speed seem to the computer like random misfires.
