Remote diagnosis and corrective actions are not easily accomplished.
First find someone who knows the motor.
Second powerwash and clean the entire engine compartment and front axle assembly.
Start with a valve adjustment, timing chain check, new valve cover gasket and finally a compression test.
next, new plugs wires points, cap and rotor. set timing.
change all fluids, gas air oil filters.
Only then, can you start even thinking about messing with the fuel injection system.
