Everyone seems to be a very knowledgeable. I have a vibration in drive when stopped, but not at acceleration. Also a small rough start. Items replaced in the last month: motor mount, injectors, fuel pump, fuel regulator, fuel filter, plugs and wires: are the purge valves solenoid evap, known to cause vibration and rough starts? Also car seems to run fine when rpm 1400 and above, and when in neutral. Car is 1999 corolla, with 60k.
