My car 307 1.4 gasoline + lpg in my car had the same problem twice, I sprayed fuel from the injector, the injector was replaced in the first one, but it was said that it appeared to be cattle, then 4 injectors changed in the second spray, but when I asked the master again, the fuel pump pumped 5 mlbar fuel and said that it was the fuel pump's engine. changed the same result, then the fuel pump has a filter there, bypassed and the excess pressure must be withdrawn due to bypass, he said that he should not change due to the pass, but he said that the price is 450 tl. what should I do after all i think i will use lpg as short as possible is it okay?
