Car loses Rpm when I press clutch

[I-luv-em-all]

This never happened before, but all of a sudden when I am stopped and I go to push the clutch in the car drops like 3-400 rpm, why?

And in between, shifts you can tell the rpm's want to drop really fast.

Any Ideas on what to do?

SEARCH, there are lots of threads about these related problems...IMO, probably not drivetrain related, hows your idle?? My idle does that but it's so common to have an idle problem or stalling problem in these cars I really don't feel like complaining about it

My idle is fine.

And these cars should not have idle problems if everything is running right. And since everything isn't running right I will complain about it, because why would you settle for less.

Sounds to me like bad ISC motor...Anyone?

Well that is weird. The motor was just rebuilt.

Also, I think it only seems to do this when the car is at normal operating temp.

Ill see if I can search a little more, any clues on what to type in the search box?

Would a bad vac/boost leak cause this??

Nope, not if it does it sitting still out of gear.

If it does that, look towards your engine.

 

[I-luv-em-all]

Damn. Well im going back to the place that rebuilt it tommorow hopefully they will fix it for free.

What do you think made it that way, or what could have happened??

The drop in rpms when the clutch is pressed in could also be caused by a bad thrust bearing. You may want to check into that.
