alain soto, DTC P1491: EGR Valve Insufficient Lift Usually caused by a bad EGR valve, the solenoid, or the vacuum regulator. You may also remove the intake manifold and clean out the ports, there might be a lot of carbon buildup. Download great diagnostics instructions from here. Hope this helps, good luck
