were there any driveability issues with this? i just rececntly had this happen to me and I am at the latest level on ids/vcm. I have driveabilty issues, surge, heitate, quirky idle and poor fuel mileage. no lite on, but ther are dtc's p1334, p0401 p0488. just last week replaced egr and ficm , reprogrammed pcm/ficm/tcm. we did rectify some of the concerns, but still left with the ones i mentioned.
