When the cars not in gear it shakes a lil bit not crazy but enough to hear my coins on the side door. now i recently replaced neutral safety switch, FL ABS sensor, and fuel pressure regulator. i go to delete codes and the abs one comes back on im assuming i didnt leave enough clearance between the sensor and axle. anyways the fuel pressure regulator code also said something with circut 1 i replaced all spark plugs (zfr7f) olds ones were a lil burnt out. i plug in the scanner to see what it said about circut 1 but now theres no codes poping up on the scanner not even abs code but the freaking abs light is still on. idk what to do anymore mind you im not the greatest on cars but i know the basic easy stuff.
