This poor S2000 sat at a dealership while they ‘ Tried ‘ to figure it out.
They just installed new parts hoping for a solution.
Injectors
MAP sensor
IAT sensor
Coils
Throwing parts at a problem rarely works. That’s why we recommend a Specialist. ie, Someone that knows the car very well.
We did track down some bad wiring and replaced and even added grounds as an added measure.
Custom also wanted a new Clutch Masters Clutch with the Install kit and Shifter rebuild.
