Hey guys. I'm having some "idle" issues which after reading the forums looks like it needs to have the "ECU recall flash" done at the dealer. Now my car battery was disconnected for a couple days while they were working on my frs. Question is, will the Recall ECU flash that they did a year ago be need to be reflashed back at the dealer?
