P2070 intake manifold tuning valve stuck open
 

I have a 05 rx8 auto and about a week ago I've been having a problem starting the car. I hooked up to a computer and it gave me a p2070 "intake manifold tuning stuck open" message. Ive looked on Several other posts about this problem but I'm not car savvy at all and don't understand much of it. Some people have told me its my battery or starter but the car turns on but it takes a few seconds to actually start. I also read about some engine recall for some 04-06 rx8s however I knew nothing about it at the time. Does that recall apply to me? I have 76k miles. Sorry if this matter was already discussed and resolved in another post. Thank you, Jason
