New Mazda 6 GJ model engine light comes after a few kilometers of drive with a very little jerk. Also it losses the power, very less acceleration after the engine light has illuminated in the cluster. Many Thanks

We need exact code numbers, not someone's interpretation of what they think it means. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Those codes mean the computer is having a problem reading the fuel rail pressure sensor, probably causing it to lean out the mixture drastically and causing the lean code. This can be a problem with the sensor itself, any and all related wiring or the computer itself and it needs to be diagnosed properly to determine the cause ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

The engine light comes with a jerk, (leaning the mixture) and after it came the engine losses its power obviously. We tried DTC again after a road test, but this time only P0191 showed up.
