Mr. GM Technician

I have a problem. Several days ago I disconnted my battery for an hour so I could clean the engine compartment and work on some lights. After connecting the battery back and started the truck, I notice the engine rpm were fluctuating and the truck sounded like it was going to die.

Did I loose all computer parameters? Do i have to take the truck back to the dealership?

Is there something I could do on my own?

 

Thanks in advance

Many moons ago. I took an autotech class.

We were told that disconnecting the battery power to the computer would make the computer "stupid" in a sense, that it would have to relearn things again. And usually within 50 or so miles.... It would be better.
