Drivers of 2008 Pontiac Solstice GXP models with 2.0-liter (VIN X) engines may come into your store with several seemingly unrelated problems.
Among the complaints you might hear are that the fuel gauge reads differently when the vehicle is stationary as opposed to moving.
Or the engine idles roughly and produces black smoke after a hot restart. Finally, the check engine light might be on with trouble codes P2610 and/or P0341 stored in computer memory.
According to GM, all these symptoms are the result of software incompatibility issues within the PCM.
Reprogramming the module with updated calibration files in the only surefire fix. Check with a dealer for the specifics of the flash.
