Are any warning lights on?
Customer: replied 3 years ago.

No there are no warning lights on and there is no loss of revs just lack of power when gears engaged and drives about 10 20 mph.

Expert:  Steve replied 3 years ago.
There is no single thing that will cause this. Common issues would be a fuel pressure problem, throttle failure, or issue with fuel/air mixture (which is informed by a number of sensors)

The best path forward to rectify the issue will be to have fuel pressure tested and the cars computer monitored in real time with a diagnostic computer which can read all inputs and outputs from all systems and identify what is out of spec
