HELP, Rough idle in drive

2001 ZX2, Rough idle in drive, pretty bad vibration.

Does it idle rough at speed, or at a stop?
It could be an engine mount, transmission mount, or both. A tune up might help some, but if the vibration is bad when idling in neutral/park, or drive, it would be an engine mount.

Thanks. I had a trans mount replaced, didn't seem to help. It's worse when I turn on the heater or air, at times it shakes the steering wheel pretty bad. When I put it in nuetral it's fine, as soon as I start moving it's fine. I'll have the motor mounts checked. What is the vct seliniod? Thanks again.

There is a TSB that covers this very thing. I have a 2001 and am experiencing the identical symptoms. The TSB can be found for free online here
http://www.fcsdchemicalsandlubricant...tsb/031515.pdf

for the 2001 in consists of slotting some holes and going thru a specific procedure to "neutralize" the engine in its mounts. The flate-rate labor for this TSB is around 3.5 hours. Different years have different procedures. I'll wait til warm weather and probably do it myself. We've lived with it this long, we can wait til spring.
