Welcome to the forum from Iowa.

Im not 100% familiar with the 5.7, but there are some basics that you should look at.

Have you changed or checked your plugs? What about your plug wires? What about your distributor cap? Do you still have your cat? Have you checked to see if it’s plugged?

Others will likely have other things to look at but those would be where I would start.

I did look at all those things except the cat.

I was told by a Chevy tech to do what he called hard reset to drain the capacitors and it worked like a charm not a single issue anymore, runs like a champ now. But that scares me even more I’m not an electrically savvy

what did this involve?

These are the RPO codes that I was asked for
Since they can help to trouble shoot

I think @GreyStone was asking about the hard reset procedure you were told to do.

He said disconnect both battery terminals touch the cables together for 30 sec to drain the capacitors and reattach both terminals. It worked like a charm

Has anyone else tried this? Are there any potential issues in it?
