EPC Problem, and having a bad driving
I have a 2009 Škoda Octavia. The engine has been swapped to a Volkswagen engine (since both brands are made in the same country/group). The original engine was a 1.6L, but it now has a 2.0L engine installed. The fuel pump is also from a Volkswagen.
Sometimes, the 'EPC' light turns on on the dashboard. When this happens, the car loses power, feels sluggish, and doesn't accelerate properly. What could be causing this issue?"

There may be an issue with your electronic throttle and EPC. If you can, scan for any stored error code(s) for a start otherwise guessing can be expensive.
