Work shaky in winters

I have such a problem in the vehicle. There is no problem in summer, it works properly, but in winter there is jolting and falling off traction. When the engine warms up or when you turn the ignition off and on once or twice on the road, it improves. You set off for a long time. I looked at the error code with little elm s, it was writing random firing error or something like that.I changed the coils last year, I threw a box würth injector cleaner at the brand delphi.depoya and set off for a long journey, it is still the same. What would this friend say? what to do I forgot to add. If I run the tool directly in lpg, it is ok. x5712020-08-17 16:46:50

If lpg is ok, there are only two possibilities. One is the gas pump and the other is the gasoline injectors. These are the two things where LPG and gasoline are completely separate. Sometimes, when the pump or injector is cold, it can work hard and then recover. Or vice versa. talip2062020-08-18 19:42:21

There are some videos on youtube you can see if you write a petrol injector test. There is a problem in one of these two, which my suitor brother said. or it could be a petrol return valve. of course I do not know where it is in your vehicles. I have a similar problem in my scenic 1. usually can be from this piece.

Some masters have a device for the pump test, as the o-rings on the return valve are often worn out, so it can be corrected by replacement.
