If this happened all at once, check the vacuum lines. A cracked or broken line will cause high or rough idle.

A bad fuel pressure regulator or a clog in the fuel return line that leads back to the tank will cause this.

What happens if your 97 Camry starts fine but wont idle on its own you have to keep it at a contant idle for a minute or two then it starts to idle on its own and after its been running it wont do it?
The issue may be one of several things. It may be caused by a clogged fuel line or fuel filter. There may also be a problem with the fuel pump, or a hole in the fuel line. It may also be caused by the fuel/air mixture being off.

What would cause a Mercury Grand Marquis 46 police intercepter to drop idle and shut off?
Take an air hose and disconnect the fuel line right at the tank and blow the "sock" off of it. There is a mesh sock that collapses and blocks the fuel line under high performance conditions. A quick shot of air into the tank will make it float loose in the tank but at least it won't constantly be a problem.

Your fuel pressure drop could be do to a clogged filter, pinched line/hose, or a weak fuel pump. You should have around 35 psi at idle and 43 off idle. I hope this helps answer your question.

Why does my '99 Oldsmobile Intrigue run great while driving foot on gas but sometimes stall due to rough idle when stopped at low idle or when I put it in reverse?
One common cause is a leaking fuel pressure regulator. When they leak, raw fuel gets into its vacuum line and causes a rich condition which can cause the car to stall, and also give a hard starting condition. - TechJK --------------------------------
