Some 1982 and 1983 Impalas and Caprices with the 3.8L (LC3) 229 V6 may experience an objectionable shake at idle in drive mode. This
condition is caused by grounded engine mounts which results from improper spacing of the frame mount brackets.
This condition can be corrected by installing 6 mm of shims between the left hand engine mount and the block. Three (3) 3/8" flat washers,
P/N 446363, may be used with longer bolts, P/N 454913, at each location. If the shake is improved, but not to an acceptable level, the right
hand mount should be shimmed in the same manner.
