She's acting up
 

Hey guys, I have a 96 LT1 w/ CC503, LT pacesetters, Fully Rebuilt, A4

Everytime I start my car if I give it gas it'll stutter and bog down. I have push the pedal to the metal to clear it out and then she runs normal. This only happens while Im driving. She still running hard but my idle is messing up a bit. But the idle problem to me goes with the bogging and stuttering. What do you guys think?
Now Im getting this code: P0400 (EGR Flow malfunction)

could it be getting stuck?

SO you have a hard start problem, where you have to floor it in order for the car start?

ALso while driving it bogs, so you have to floor it again?

Is this right?

You need to clarify this a bit better and get back to us.

No I mean when Im driving. The startup is fine.
