I have a 1997 chevy k1500 it has the 5.7 vortec in it i recently replaced the injectors the fuel filter and the fuel pump. I also replace the distributer cap and rotor. The problem i am having is it keeps giving me the fault code for miss fire on cylinder #8 im really not sure what to do now. The truck still runs pretty good but the check engine light flashes and gives me that code.
My car has 202500 miles.
My car has an automatic transmission.
Hello. A continuing misfire on #8 suggests a bad plug wire, a bad spark plug, or possibly oil leaking down onto the #8 plug, shorting it out. Also, if one plug wire is bad, replace them all. Given your mileage, you should be looking at the plugs also. To have this resolved, I recommend having a certified professional, like one from YourMechanic, diagnose the misfire in person to have this corrected.
