    Recently, during normal driving on highway (40-50 mph), my 03 Concorde has an occasional, momentary sudden ‘power surge/jerk’, after which it returns to normal. Has 135K miles, very well maintained……After checking and inspecting all possible causes (injectors are clean, plugs and coil packs fairly new, air filter new, fuel pump and flow seems ok, MPS just replaced, on highway it drives beautifully), all appears to be normal! I replaced Trans fluid very recently, shifts perfecto, but I do suspect the problem is in the power train somewhere. I’m stumped! Any suggestions what to do next?
