Maxima running poorly after heater core replacement
Hello all , I'm new and look forward to learning and sharing with any and all enthusiasts. I've got a 2004 Maxima that I replaced the plugged heater core on. I had the ECU out on the bench for a couple hours and battery disconnected. Got it all back together and now the car runs like crap. Am I missing something?
