[Resolved]  Maruti WagonR — Missing problem

Sir,
I have purchased my Maruti Wagon R LXI DUO on date 13.12.09 from Tanya Automobiles LTD. Meerut. The engnion no. of my car is 4591403 & chasis no. is 766502. Previously I have owned a Maruti Alto LXI & replased it with the Wagon R. So u can say that I am a loyal costmer of Maruti but my loyelty diminished after purchasing my new car wagon R.
Till first service the car was working ok but after second sevice when I got my car on date 04.05.09. I fill it with the petrol & the LPG gas from company authorised petrol pump & was moving on my local tour the car had started giveng missing problem on LPG gas then I shift the inginition to petrol the car was running properly. after returning from my local tour I give the car to the Service station ( RAJ SNEH AUTOMOBILES - MEERUT ) and complained about the missing problem. in the evening I got my car from the survice supervisor. he said that the LPG gas was not pure that why the car was missing we have cleare the LPG Gas tank & now the car is running fine. but when again I filled the car with the LPG gass again I have faced the same problem. As the car was missing heavilly and was not running properly, then I again go to the service station & complained about the same. The service supervisor again told me that the car will be delivered to you in the evening & in evening when I got my car the service advisor told me that the all Spark Plugs were not work properly. So we replace all the Spark Plugs & now your car is ok.
Then I take my car from him & go to my home. Next day when I was coming to office from my home again the car has started giving the same problem.
Now the problem is this when I run the car on petrol it works fine & when I shift it to LPG it starts missing & it's very tedious to drive. Now from previous Ten Days I am running it on petrol.
I have also enquired about the LPG supplied by the Petrol Pump & the result were satisfactory as some of my friends are also using the LPG gass from the same petrol pump as there is only a singal petrol pump of LPG in Meerut.
So my suggestion for Maruti is that the service stations are not providing proper service for the LPG Vechile's. Or if there is any Manufacturing/Part problem then please ractify it because people like me can be saved in future because it is very expensive to run the car on petrol that's why people are purchasing the DUO Version.
Waiting for your positive & immediate response.
