    88 Pathfinder in failsafe mode, computer says injectors are bad
    Hello! I have an 88 Nissan pathfinder, 3.0 V6, telling me one of the injectors (TBI) are bad - computer code 51. But, I took them off and had them tested, and they were both good. What could be causing the computer to say I have a bad injector when it appears to be not the case? Or, how can I get the computer to bypass the failsafe mode, which it doesn't allow me to go past 2750 RPM? Thanks, Scott

    Reset the ECM and see if it throws the same code again. Remember, ECMs are NOT bullet-proof! I normally recommend replacing them every 120,000 miles or 10 years, whichever comes first. You may want to look into a remanufactured ECM, with a lifetime warranty, if you can't find any other explanation.
