What could cause surging and loss of power in a 2009 Volvo S80 T6.
My S80 engine light came on and car shut down while driving. The mechanic said bad ignition coil was causing the fuse to blow. The coil had a burning smell and a hole in it...replaced all 6 coils ($900) and the car is starting okay and no engine light but it has no power when gas pedal is pushed down. I'm scheduled to bring it back on Monday and wonder what the problem might be now.
