### ⭐⭐⭐⭐ Cat and Oxygen sensor cleaner.
*by W***S on 1 November 2024*

Whilst I got exceptionally good emissions results, like 34 ppm out of 330 allowed and the car is running really well It did not fully clean up the Oxygen sensor that was dirtied by a spark plug pencil coil coming loose. I still get a hesitation on acceleration if I give it full throttle quickly. Accelerate gently till half speed, 3000 Rpm and then give it the rest and it goes well. This is on a 21 year old Renault 1.8L Scenic. I will have to bite the bullet and change the sensor but it is a PITA to get to. The Wynn's petrol clean extreme is really good and has extinguished MIL lights on my other Scenic. The fault log on Torque is showing a faulty up stream Oxygen Sensor, hence trying this first. It is most definitely worth a go first before major surgery.
