    Help with 1404 code

    Just got a 99 4door blazer on the 14th stopped to fill it up made it a mile and the service engine soon light came on. Had autozone and a friend check the code its 1404 the EGR valve is showing in a stuck open position i pulled it off today and the pintle moves freely. My 10day runs out in 2 days not sure if theres another issue or the EGR is bad it looks new so maybe its an off brand where the spring? that holds it closed isnt tensioned correctly so the exhaust running to it just pushes it up. Any help is greatly appreciated, also if i have to get a new EGR should i try to get an AC delco just want the light of so i can get it inspected.

    In some cases, This code will set if the sensor return to the PCM is damaged.
