Hello, newbie here, I have a 2001 mazda 626 I recently purchased knowing the trans. needed rebuilding, had it rebuilt but when I drove it home it now has a bad vibration in the engine at idle. 3 mounts were also replaced, anyone know what the problem could be ? Thanks for any help.

Did it have the vibration before the trans rebuild?

No, it did not have any vibration at all. The trans guy is wanting to raise the idle speed, I believe this will only mask the real problem.

That's not the answer. Something may be grounding out somewhere, possibly the exhaust or motor mounts.

Thanks, I am going back to his shop tomorrow, I was wondering if there was some type of " idle " sensor that could be bad but seems to me it has to be the trans or eng mounts since it was smooth before. It smooths out as soon as you pull off & are moving but as soon as you stop it vibrates very bad in drive or park. Thanks for your help.

It really sounds like you have a bad motor mount here.....
If you have a floor jack, put it under the engine pan with a block of wood on it and while it's in gear vibrating, gently jack the engine by the pan to support the weight, if the vibration goes away, you have a bad mount...........
