1 Answer


did you reset the computer after you replaced the valve ? Unhook the positive cable from battery for fifteen seconds ,then reconnect . vacuum line error is possible but if it's like most newer vehicles the lines preety much route themselves . If one is stretched or hass too much slack I'd start looking there .
