I just put a new bad mab header on my 2.2 and now the engine stalls out sometimes the rpms jump. theres a huge hole in my flex pipe but that will be replaced with my new downpipe zzp. but coul;d it by chugging because of the 02 sensers not getting enough air?

02 sensor tells ecu if you are running rich or lean, mine was just fine

chances are that hole is ******* with something

First O2 should be before the flex in your header. So it shouldnt cause problems
