I have a Renault Captur from 2016 with a petrol engine. I'm having a slight trouble when taking off. With the car stopped I shift into 1st gear and slowly release the clutch while at the same time slowly pressing the gas pedal. After this, I fully release my foot from the clutch and only use the gas pedal. This is where I'm having issues.
After fully releasing the clutch, I am at about 2000 rpm and usually at a very slow speed like 13 km/h. I slowly give it more gas in order to gain more speed, (I've tried until 4500 rpm-ish), but the speed stays practically the same, maybe it reaches 17 km/h. This is driving me insane. Here I am in my car making my engine roar like some mad behemoth but my car won't go any faster and it's getting really frustrating.
I want to be able to go faster in first gear because when I'm stopped at a red light and I take off, the cars in front of me take off very fast, and I go very slowly, and I feel like I'm being a nuisance for the cars that are behind me. If I change to 2nd gear at about 2000 rpm when in 1st gear I still go slow, because the car isn't moving fast enough so that I can take full advantage of being in 2nd.
My car has eco driving, and I have disabled it and tried again, but everything is still the same.
I've never had this type of trouble before. Is my car faulty in any way? Or am I doing something wrong?
