Car goes into limp mode on highway. Shakes very bad and I lose power to my car speed going from 65-70mph to 30-40mph forcing the car trying to get to a safe area to see why my car suddenly lost power. After dodging all the close call accidents from me trying to pull over I come to a complete stop and car is shaking out of control so I turn it off and turn it back on but my car still shakes out of control. After sitting on the side of the road with traffic zipping past me for about 30 minutes I turned my car back on and the shaking went away. Days later the car did it again but I was in city streets I pulled over and turned off the car and waited 30 minutes again. The next day I took it to a mechanic shop and told me the high pressure fuel pump has gone out and there is metal shaving in the gas tank and in the lines. To repair my car it would cost me near $3,500!
