The Infamous Fuel Injector From Gm

[ronaundi]

1997 GMC Sonoma extended cab v6 4.3 liter with 160 k miles

 

I have misfire codes and within the last year I have replaced:

 

-fuel tank

-fuel filter

-direct fit cat

-downstream o2 sensor

-new upgrade spider to replace the poppet style injectors

-ignition coil

-plugs/wires

-rotor/cap

 

The first day after replacement of the new spider unit it runs like a champ,after that the random misfire code P0300 again.The truck runs a lot better but these misfire codes are drivingme nuts

 

If anyone has ideas feel free to post
