Knock Sensor Problem in a Peugeot 106 Petrol Engine

Hello, I have a 1998 Peugeot 106 with 400000 km. I'm experiencing some problems with the petrol engine. After the car came back from repair, it started misfiring on petrol and won't accelerate, but it runs normally on LPG. The mechanic didn't install the knock sensor and the sensor is currently loose. The sensor on my car is different from other Peugeot 106 1.4 sensors sold and it's a long type. The loose socket in my car fits the sensors that are sold. Everything related to knocking in the engine unit has been replaced, but the problem persists. How can I solve the misfiring and acceleration problem on petrol? Can you help?

The suggested solution is to properly install the knock sensor, as it is essential for detecting and preventing engine knocking, which could be causing the misfiring and acceleration issues. After installation, clearing error codes and testing the car on petrol is recommended to see if the problem is resolved.

Start by securing and properly installing the knock sensor, as it plays a crucial role in engine performance by detecting and preventing knocking. A loose or missing knock sensor can cause misfiring and poor acceleration. Once installed, clear any error codes and test the car on petrol again. Let me know if this resolves the issue or if you need further assistance.
