So my car has been running rich for a while now. So I finally took out the ECM to see what kind of chip was in there. Come to find out it is a stock chip I'm assuming because it says Delco BBKJ on it. The car has 42 pound injectors on it after verifying the part number on the injector. Is this the reason my car is running so rich.
