Ok, got a question. I have an 89 GT and I've been chasing code 33 for months and I cannot for the life of me figure out how to get rid of it. I have replace all EGR components chased wires, and they are all good. I have placed all vacuum lines. I have placed the EVR solenoid 4 times including the thermators and nothing helps. I'm getting vacuum from the intake to the EVR solenoid but for reason no vacuum from the EVR to the EGR.....WTF!!
