hi i have a 3.1 v6 in my 1991 camaro and a couple weeks ago i had to replace the intake gasket so i took it apart replaced it and put it all back together but now with the vacum leack is gone the engine is scruing up it idles fine but when i give it gas and run it at about 3500 rpm it leans out it pops and cracks but once i get off it works fine only happens under load or high rpm sombody [plz help i ran out of ideas] thanks fellow thirdgenners.

 

double check to make sure you got all the vacuum lines hooked back up, especially the one for the fuel pressure regulator.
