P2318
Ignition Coil "G" Primary Control Circuit Low
DTC P2318, sometimes indicated as P231800 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing ignition coil "g" primary control circuit low.
The ignition coil "G" primary control circuit low may be caused by a defective ignition coil, a shorted ignition coil primary wire, or a defective ignition coil driver.
The most common solution is to replace the ignition coil. If the ignition coil is not defective, the primary wire may need to be replaced. If the ignition coil driver is defective, the entire ignition coil module may need to be replaced.

While crossing a four-lane road, the accelerator pedal went limp and caused the engine to become unresponsive. The car would not accelerate and barely made it across the lanes of traffic to the median safely. The check engine light illuminated and when placed into park, the engine revved to approximately 2500rpm without my foot being on the pedal. I turned the engine off, and restarted it only to have it rev again on its own to 2500rpm. It took 5-6 attempts to restart it before the engine idled appropriately and the accelerator became responsive again. The check engine light remained on and obd code P2318 was returned when i plugged in a scanner to the port. This is not the first time this event has occurred; it has been random and sporadic for about 8 months now, sometimes occurring as often as 3-4 times per week to going 2 months in between episodes. Speed does not seem to be a factor, it's happened at both freeway and parking lot speeds, in all kinds of weather and at various temperatures, with the cruise control on and with the cruise control off.
