Fuel Injectors
Does anyone know how important matching the serial numbers on a set of injectors is? I have an S10 that I put used injectors in not paying attention to the serial numbers. Ever since it runs rich. I got a new set of injectors, but only two out of the four worked. So right now I've got injectors with at least three different serial numbers on them. I read somewhere that, when replacing injectors on an S10, it's very important to match the serial numbers due to the different flow rates. Can someone please tell me if this is true or not?
