When i pulled the codes on my car i got a 511 which is a pcm rom failure. Does this mean that my eec is not working right and i need a new one or is there another problem. When i had my car dyno tuned, they said it might be the maf so i switched the maf to a different one and it didnt do anything unless the used maf i got was bad also. Any suggestions?
