The codes flashing on my ECU are "7" (Throttle Position Sensor) and "9" (CYP sensor). I'm not sure where either of these sensors are yet. Does anyone happen to know? (B16a) The car has been running a little rough lately, kinda sporadiclly. Seems like it's missing. I'm not sure if a cap/rotor/plug change would cure this or if it's because of one of these sensors. I'm not sure what these sensors do and how they affect performance.
