I started my vehicle up after work and it was idling rough but then stabilized so I payed it no mind. Soon as I merged onto the highway when my check engine light started to flash. I immediately loss power and the vehicle started to decelerate. I turned on my hazards, pressed on the pedal to accelerate but the vehicle was bogging and wouldn't accelerate pass 50mph. I safely got off on the next exit and shut off the vehicle. I turned the vehicle back on and made it home safely. This is the second time this happened. I changed multiple parts on the vehicle since then, yet it continues to happen. I took the vehicle to the dealership and they could not figure it out.
