Twingo goes out and takes bad gas

Hello together, my Twingo Bj. 98 got a little angry this morning. He jumped on and when he came out in the low speed range again. I restarted him and again the same problem. Then I gave a little bit more gas at the start again, but he didn’t take the gas properly. He stuttered, but when he reached a higher speed, he took the gas better. When I took the gas away, he went out again. Then I passed through our zone 30 more times. can it be because yesterday it rained with us all day and all night that something got too wet? When I arrived at work (after about 45 km, of which 35 km highway) he ran again without any problems, stayed at the traffic lights and took the gas back to normal. Does anyone know what it might be?
