Does anyone here use iDrive? Throttle lag started up not too long ago and it's just getting worse with further delayed reactions..even manual mode is a bit off..any positive results with iDrive? Is it actually legit? Before you mention my maf sensors ect, did all that including K&N air filters and throttle body 4-5k miles ago and whenever I clean my maf sensors they get wonky for a while so I'm absolutely never touching them again.
