The vehicle is Pejo 206 1.4 8v automatic Gasoline+LPG. The problem is that after the vehicle has warmed up sufficiently (after 5 minutes of driving), it makes a knocking noise when you press and release the gas pedal as if there is a gap, that is, it is unrelated to gear changes, sometimes when I release the gas pedal there is a slight hitch when downshifting, but it occurs when you press and release the gas pedal. Thereupon, the transmission and engine upper mount were changed, a few lower set parts were changed, tie rod end shaft etc. It was not fixed, they said the lower mount is fine, it was not changed, but I looked at it myself, there are cracks in the mount, I took it to 2 mechanics and had them checked, they both said the lower mount is fine. The problem is not felt much at speed (+60 km/h). It is generally excessive at low speeds and low revs in stop-and-go traffic and it is more severe when using LPG. I went to a mechanic and he said it was due to the transmission. I went to the transmission mechanic and he said it has nothing to do with the transmission and it could be the axle. I went to another mechanic and he said it was due to the mounting or there is a gap on the right axle. He said we can change it, if not we can change the mounting. I said the upper mountings were changed and he said we can try changing it with the original one. But who can I trust? There is no return for these operations I had done. I mean, it is money. I think it is called cut-off. It probably does it at that time. The vehicle is crashing every time I press and release the gas. Is there anyone who can help?
