I'm having some kind of flow issue with my EGR system on my 96 LT1 firebird formula. I've looked over the system as much as I can, but I can't seem to find the dang problem. I replaced the EGR valve already, since the car has 120k on the odometer and I was thinking that the EGR valve itself is probably just old.
But I'm getting no vacuum coming out of the very top hole on the EGR valve. Would that spot be pulling vacuum? Also I have longtube headers, but I don' think that this is the type of system where that would matter. Not sure though.
