would I still get an error message from the ecu? Sorry total noob here. Ive only owned chevys. Mostly hand-me-downs. Do I need any special equipment to get ecu reading? I know this much: the chip was reprogramed, the injectors were replaced 5000 miles ago(3yrs ago), the new starter is a remanufacture not nissan, flywheel is aftermarket. If the injector went bad would I know that while I was driving? Drove it for 30mins(wasnt racing either) and it ran fine. Started it back up an hour later and it just putted.????????
