Is the 2016 2.0 Premium version set to not go faster when you press the accelerator at 120? Could any knowledgeable experts explain?

I've had my car for four and a half years and it's only done 36,000 km. It's a 2019 model with the 4J11 engine. Recently, when I start it cold, the engine struggles a lot. The RPM doesn't go up immediately, and the needle wobbles between 500 and 1000 for a few seconds, making it feel like it's about to stall. Then the RPM suddenly jumps to 2000-3000 before settling back to normal idle after a few seconds. There are no warning lights, and once it's running, everything seems normal. I've cleaned the carbon buildup and throttle, and checked the intake for leaks, but the issue persists. I'm not sure what to check next. What should I look into?

What could cause the 2014 Peugeot 308 to not spray windshield washer fluid? Is it the lever on the right side of the steering wheel that needs to be lifted forward for a few seconds? I can't find the spray nozzles, so I'm considering using a needle to check if they're clogged. Any advice from the experts?
