Exhaust sensor light and oil light turn on when turning!!!!

[Mike1981FiatSpider]

Hello, I have a 1981 Fiat Spider convertible. I am the original owner of this car but it recently has been doing something interesting that I cannot figure out. Whenever I am making a turn, the exhaust sensor light and the oil light on the bottom of the rpm gauge, light up.
Both lights light up at the same time and the car begins to drive rough. After less than a minute the lights turn off and the car runs smoothly again. I've looked in the engine to see if anything is loose and cannot find the problem.
Has anyone else had this problem or does anyone know what I need to look for?
Thank you in advance.

These kind of problems (lights/etc going on and off for no good reason) usually are caused by an open ground to the circuit controlling the problem light/etc. This is a 40 year old car. I'd go over all of the wire connectors and check for a good crimp. I use "3n1" on the connectors.

Check your oil level. My '75 would do this when making hard turns when the oil level was low. Also, the oil pressure sender may be going bad.

This is a very unusual problem. Especially the car running rough at the same time and the lights going on.
The lights receive power through the start and run position of the ignition switch. The ground for the oil pressure light is provided by the switch mounted on the oil filter housing. The ground for the exhaust gas sensor is provided by the box mounted to the pedal bracket near the gas pedal and from the warning light test circuit. So I don't think your 3 symptoms are related by a single wire other than the engine ground that connects the bell housing to the under carriage floor of the car.
The wires from the engine compartment pass through the fire wall near the gas pedal. I would closely inspect there for wire chaffing. I would also inspect the 6 cavity connector on the ignition switch pigtail.
