The car runs great on surface streets and the free way when in gear but when im on the free way and get on the off ramp and take it out of gear to switch to a lower gear to slow down i see the rpm needle bounce up and down a few times and then it will stall. It doesnt stall when i shift into the lower gear it stalls in between me being in 5th gear and trying to switch to a lower gear like fourth. What can be the problem because i havnt been able to find what cause it? Thank you for any help you can give!

Will it idle ok otherwise say at a stoplight? Possible idle air control issue or vacuum leak,

It seems to idle fine for the most part! But it doesnt idle at 900 rpms like it usually should. And one mechanic that i trust checked the vacuum seals and he said they were fine so any other thoughts ?

As stated "idle air control" valve needs to be checked.
