Default 5.3 running very rough
Hi my name is Justin, I have a 99 Chevy Silverado with a 5.3 and it won't run anymore. It started mis-firing on #7 intermittently but would run good when it warmed up. Now it basically doesn't run at all. I made a youtube video of what it's doing hoping this is a common problem and maybe somebody can help me.

Try disconnecting the negative battery cable for about 30 minutes and then hook it back up. This forces the computer to re-calibrate. That may help.

Just an update. It was the intake gaskets. I changed them out to the new teal ones and it runs great. Easy fix.
