well since the SEARCH function is not working properly tonight, i have a question.. can a bad rear tranny mount make my car feel real rough when idling? what about all mounts... when they are bad are they supposed to make the car vibrate rough? first off i thought it was my iacv going bad but changed that out, then i thought it was my pcv valve, so i changed that and now what?

 

Yes, if you have a mount broken or cracked enought it will cause vibrations.
