If I don't let my car warm up long enough and I begin to drive it wants to quit

(1990 Lexus LS400)
If I don't let my car warm up long enough and I begin to drive it wants to quit between 40 and 55 miles per hour, also during the day when I start driving right away it idles at 500 to 1000 rpms back and forth as I'm driving for a short time like the governing idle is messed up. What do you think is happening? Thanks for any advice
What seems to make the problem better or worse? its worse when the engine is cold
How long have you had this problem? for about 3mths

You will want to start with basics like checking for vacuum leaks, fuel pressure and condition of spark plugs. This could also be a throttle body or tps issue. If you don't work on your own car then use this link to find a good shop near you.
