Hello, I'm a Nissan Tiida owner, and I'm encountering acceleration issues. I've replaced the spark plugs, air filters, transmission fluid, engine fluid, and the Fuel Assembly, but the problem persists. I haven't diagnosed the ignition coil yet, so I'm wondering if one of the coils might be faulty. For example, when I was in traffic with my foot on the brake, and I released the brake and pressed the gas, the car surged for a second and then settled. I noticed this tends to occur when the vehicle is cold. It mostly happens at low speeds. What could be causing this issue?
The same thing happened to me u could 1.check throttle position sensor, 2.air Filter or 3.throttle body may need cleaning please remember to subscribe.
