Video tutorial

In this video, we see how a broken gasket between the throttle body and the air filter of a Lancia Ypsilon has negatively affected the ignition of the car's pistons. In fact, this car had a problem where the pistons, alternately, were not firing, causing the car not to run. We have to remove the air filter box, the duct bracket, the oil evaporation tube, and the oil recovery tube: we find that the gasket that connects the filter box to the throttle body was practically destroyed, allowing air to pass downstream of the filter, into the throttle body, causing the fuel values to be off. We clean around the valve and inside with a specific cleaner.

We replace the gasket and reassemble the air filter. Now the engine works at 100%.

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
