Default 90 Camry - shaky idle/low torque

At idle the engine shakes and seems low on torque. In reverse it has a
lot of trouble backing up a hill. Off the line itís slow to get going
like it doesnít have enough power, like it canít breathe or isnít
getting fuel. Once I get the engine up to a good RPM it just takes
off. Sometimes from a cold start the engine idles-up and the problem
goes away, but once the engine warms up the problem comes back.

Also, once the car starts to accelerate at a good pace, it
occasionally surges. Itís like some componant springs to life and
gives something more signal or air or fuel.

Could this be related to IAC or the O2 sensor? Would a low idle speed
cause this? What other sensors are involved in adjusting the fuel-air
mixture and the idle speed? Could bad injectors do this?

Cars were so much simpler when all you had to do was adjust the carb,
distributor and choke
