You should try to clean the throtle valve and see if that works. The lambda sensor will increase the fuel consumption and the pollution. It's better to replace the sensor.

I would expect a "check engine" light and a code if your O2 sensor was bad. You checked codes, right?

My 94 mx6 keeps stalling


I would not recommend throwing parts at it.
If the computer or O2 sensor is the problem you should have a check engine light on the dash. Usually the EGR valve causes a problem when you are slowing down not just on turns.
If you have not replaced the fuel filter this year I would do that to scratch it off the list.
The throttle position sensor could be failing but not to the point of turning on the check engine light. It can be tested with a meter.
You need to find out if you are loosing fuel pressure or creating a vac leak when the stall happens. Could be a vac hose or something that is moving when you are moving the engine.

Try checking the codes. You can do this at part stores like auto zone for free. It might be the maf sensor or if it says lean o2 sensor than it's the fuel filter.

Throttle/Idle/running problem - wants to run too fast, or stall out


RPM's up and down check EGR valve and sensor. EGR valve and sensor control idle. That's why your getting the surging on rpm's and this could be giving out the other codes. If mass flow was bad car will not start and the same for the map sensor. O2 sensor measures gas and air for right mixer. TPS controls 0-60 speed as in throttle respons.

2007 Suzuki sx4 engine light on after oil changed, How to turn it off?


The solution is that when the oil filter is removed, oil gets on the O2 sensor and ruins it. Must cover the O2 and that keeps the oil off. To keep the check engine light off, is to replaced the O2 sensor. Problem solve. Later on sx4's they move the O2 in a different spot. I work on Suzuki cars. Don
