Some customers may comment about objectionable engine vibration during idle. Vehicles equipped with automatic transaxles may also exhibit a harsh 2-3 upshift. This condition may be more noticeable when the engine is cold.
Condition may be caused by change in material properties in rubber isolation cushion of the engine mount assembly.
Perform the following procedure to check the engine mount and, if necessary, replace the engine mount assembly according to procedure in this bulletin.
Important: To ensure accurate measurement, hold the straight edge flat against the machined, flat top surface of the front cover. Make sure the vertical scale rest on flat surface of the engine mount assembly, not on the fold-over tang found on some engine mount assemblies.

Damage tot he front cover may occur if the stud id driven with the nut and does not sufficiently engage the front cover threads. (Refer to "Engine Mount Front Cover Stud(s)" in the "Powertrain Mounts" section of the "Chassis Service Manual.")
