As the title says, school me please!! I threw a code, (P2146 front bank of injectors). I checked ohm's on all three front ones. 2nd one is bad. Here's my question since I have heard different things. Since it failed electrically, I have been told I would be okay with just throwing one in there. I was told that if it failed mechanically, then I would definitely need to replace all 6. Any input on this or suggestions? Truck has 140k on it, run a small tune. Other than that truck is stock. (only ran the tune the last 30k miles) Thanks in advance for any insight.
