Trying to fix error code 0302 (restricted flow to the egr) on my 1999 Maxima.When I pulled the hose coming from the throttle body to the EGR valve,anti freeze fluid puored out. Is this normal? I ruled out the Electric EGR valve being bad ,after testing out the coils had like 23 ohms on 1-2, 2-3, 4-5, 5-6 and the two incoming red wires had battery voltage.Please help.
