Hello guys. I need valuable comments and experiences regarding the problems I mentioned in the title. I am having some problems with my 2000 model 1.4 automatic vehicle with LPG. I haven't been able to show it to a master yet. Frankly, I want to have some knowledge and go like that. Unfortunately, the person we go to as a known master sometimes sees us as a goose. However, when I stop after a certain period of time and start the starter after about 20-30 minutes, it works too late. (There is information about the possibility of leakage from the lpg regulator in general. When I checked the hose coming out of the lpg regulator and entering the intake manifold, I could not detect any number of etc.) ** * Another problem is when the vehicle is idling for the first time, especially with gasoline, the vehicle shakes excessively. (I cleaned the throttle and the idle valve, but nothing changed) *** And when the vehicle is idling, it feels like it will choke-stop and then the speed increases. There is no problem when I give slow throttle.In addition to this question, when the vehicle is at idle, when the speed is brought to 4-5 thousand and the gas is released, it goes down to very much below the speed and it seems to stop (it has stopped a few times) *** finally the vehicle is on the straight road It eats gas smoothly, accelerates, no problem. but when it comes to the ramp, it seems like it dies. the heat is coming to the 110s. (no water reduction in vehicle) * Some sources have information that the oxygen sensor may cause this type of problem. but the fault light does not come on in the vehicle. * I think there may be a problem with the spark plugs. I have not been able to disassemble and check them yet. The problems have been a bit long, do not mind. but as I said before I take it to a master I want to have a more or less idea. so I need your valuable comments. Thanks to everyone who took the time in advance.
