I took my 2003 saturn vue v6 3.0L to the shop and had the o2 sensor and all the sparkplugs replaced bc the technician said those were the codes that were coming up. Worked fine for a few days then the service engine light came on so I took it back and the same exact codes came up for the cylinder misfire and 02 sensor so the tech said it most likely a bad ecu. Is that what it is the ecu? If I buy a used ECU and have it put in my car I dont have to get it reprogrammed if it is off the same year make and model right? If I replace the ecu are there any other mandatory parts that need to be replaced with it? Please help I spent all the money I had at the first shop and cant afford another
have the same problem?
