my egr valve was bypassed, i tested it and it works it wasnt done right so im going to hook that up. also i have to go get a new solinoid because i dont have one on the car, it blew my head gasket because it got way too hot right at the egr valve side. and im running rich because i found my coolant temp senser wires barly hanging on. so im going to fix them 2 things and i should stop blowing head gaskets
