This sounds like it may be as simple as cleaning the water or gunk out of the gas tank which is what I always do 1st because it's easy and inexpensive.
If your fuel is contaminated with gunk, grime, water and/or bottom junk like rust this will cause stalling!
It's most likely bad fuel or clogged injectors so....
Fill the tank with High Test, Add some dry gas and a good fuel system cleaner or 2 or 3 and this should dissolve all the gunk and clean the injectors!
Read & follow the cans' instruction carefully.
If this cures the problem never let your gas tank get below 1/4 and especially never run it to empty as this is when the gunk and/or water will enter the system!

I know it sounds to simple but try it please! It's cheap and works 90% of the time!

Rough idle chevy 350


Have you checked/replaced the O2 sensor(s). They produce the data that your computer reads. Bad/clogged O2 sensors will trick the ECU into running lean/rich.

Before we both knock ourselves out with fuel injector testing. Hook up a Digital voltmeter (DVM) to upstream O2 sensor and lets see how she is burning. Remember positive lead of DVM to signal wire and negative lead to ground. Anything above 550 mV is rich anything below 350mV is lean. Be mindful that an exhaust leak the size of a pin hole in this region can cause a rough idle. A healthy reading should bounce between 550mV and 350 mV.
Next to test is O2 is working block off air in take making mixture rich and see what O2 says about it . Then pull off a vacuum hose (a lean condition) and see if DVM drops to 200to 300mV's.
Keep me posted.

1998 camry 5sfe engine, surging at idle


Check for air leaks in the vacuum pipes in and around the inlet manifold, they have a habit if going brittle and splitting.
Another possibility is the temp sender , if the ecu thinks the engine is too cold it will compensate causing the engine to " hunt". This can be something as simple as a worn radiator cap seal letting air into the cooling system and tricking the sensor.
Hope this helps, Marshall

yes an o2 sensor can cause those symptoms so can a minor vacuum leak --bad ignition wire -clogging fuel filter --sticking egr valve etc.

Check your idle air valve, maybe your air filter needs to be changed. EGR valve may need to be checked at as well.
