Hello friends, I have a 2005 model 407 sw vehicle, 2.0 engine and mental brand LPG. In the morning or when the engine is completely cool, it kicks. There is no problem after warming up. There is no loss of water in the vehicle. The spark plugs took the new temperature sensor to the new service. 80 TL of workmanship will be taken, I did not leave it, of course, I would appreciate it if you help friends who have such a complaint or knowledge ... meanwhile, the vehicle is automatic and when we give gas during kicking, there is no smallest problem.

Observe idling engine, injectors may be clogged. A positive conclusion will be reached.

There is no idling engine, there is an electric throttle in this vehicle.If there is no problem in the idle, it does not eat gas and it does not go.

look at the service they have forgotten what country they live in 60 lira per hour.
injectors spark plugs ok may be caused by right lpg
Is there the same problem if your vehicle is working on gasoline?

There is dirt in the injector, I also had a misfire. 90% of my kicking with würth injector cleaner is counted as over.

[QUOTE = dukenukem82] there is dirt in the injector I had a misfire too. My kicking with würth injector cleaner counts 90% over.





If there is dirt in the accumulator, is there no reduction in traction when driving on normal gasoline?

Master yesterday I told you. We have an experience that we say, I lived the same thing. If you hit the gas a little more, you won't notice it. Normally, you get 50% performance when you press 50% of the gas, and you get 50% performance when you get 60% when the blockage occurs, and the remaining 10% clogging creates a misfire problem when you don't press the gas. It's that clear.

Hodja, what did you do? Did you solve the problem? What did you do? In the meantime, I have the same problem in my car. We tried something, but we still haven't found a solution.

I could not cope with the problem, I sold my car, got rid of it :) but I used the gasoline additive again, the ignition coil did not change. ..

just doing it in the mornings only in the mornings, there is not the slightest deviation in idling, gas feeding is super, throat butterfly, spark plug coil, filters, curve valve, ecu update is not all done, the service top cover will be opened, there is an institution in 60 thousand vehicle

I am saying this why nobody believes it. In LPG vehicles, after the system is installed, the lpg brain and the car's own brain are matched, but the lppg brain is trying to outperform the car's own brain in terms of fuel consumption, and since the data coincides when it is cold in the morning, it is not a problem, but the air flow is very problematic. motor starts to misfire. The reason for this is that the fuel consumption map in the LPG brain and the fuel consumption map in the car's own brain constantly disrupt each other. The solution is to love the lira 20 lira each day or buy a string and get comfortable: D, for example, I am one of those who sell my lpg car and get promoted to diesel.

And I said this is not the same in every car. I do not understand how it is, but it does not cause trouble in volvo.

It doesn't improve without resetting the brain. Have you re-softwareed your brain?
