That is really strange I would say the problems were not related I have had a crank sensor go I think we all have. AS for the throttle position sensor thats a new one for me.. The people who had full throttle problems with the SB returned them and got new ones or there money back. To date I think I have only herd of two people with faulty SBs I have had them on both my cars now and never had any problems. As for the Manual version yes it is very agressive and not linear sometimes its not even fun to drive like that.
