i took my car in yesterday for my sub going out, my headunit getting stuck and my ecu to get reflashed... well the guy at the servuce counter asked me why i need to get my car flashed.. i said cause my car hesitates when hot.. well i call this morning to see if my car is done and the service guy told me that my car is driving fine without the flash.. i was like here we go.. i told the service rep that the car does it when the weather is hot.. now the car is driving more normal since the weather here has gotten much cooler.. i think i might be out of luck.. the dealership is john finger mazda in greenville,sc
