I am getting a vibration when the car is in drive but stopped with foot on the brake. I changed the motor mounts last summer which helped a lot but the vibration is still there and seems to be gradually getting worse. The driver's side drive axle was changed maybe a year ago but no the passenger side. I'm not sure if it is an engine problem or transmission problem, sensor, vacuum hose or whatever. Hoses look ok, valves. It seems to run pretty smooth when in park or neutral though. I don't have a computer to read any codes but engine light is not on. If I bought a scanner would this type of problem show up in the codes?
