Problem With The Engine Rpm In Palio 1.6 After Lpg Conversion

[HAFI]

hey,

i had recently installed an LPG kit for my FIAT Palio 1.6.It was realy a difficult job to get the right mixture(a part of the LPG kit which controls the gas flow into the air intake pipe)kit since the engine being so powerfull.

After the install there seems to be a problem with the rpm of the engine...when the RPM goes high(say above 3000) it comes down slowly...and if we are at higher speeds,the rpm doesnt go down as it usualy does...it goes down very slowly.But it behaves normaly when converted to petrol...i now have to keep on pressing the clutch until the RPM goes down...the engine continously keeps on roaring as rpm stays high for a long time...

I went and had a talk with the people who fitted in the LPG kit.The guy told me that the sensor(one which controls the air intake and rpm ) is damaged and have to be replaced.But when i went to the FIAT authorized service staion,the people over there told that there is no problem with the sensor(they did not even check it) and if it shows problem with LPG ,it will definilty show problem with petrol..

But the guy who fitted the LPG argues that it wound show any problem with petrol because when we give the acclereation the injector injects fuel and when not given it wount inject fuel and hence the RPM goes down eventually and in petrol we cannot notice this change even if the sensor is damaged(I also feel that he is right).

I happen to see one more trouble now...the the RPM doesnt go up when the A/C is on(both in petrol and LPG)..Normally the RPM should go up so that it can balance the load of the A/C..It doesnt do so..and the engine knocks when the A/C is on.....and now there is a starting trouble too(both in petrol and LPG)...i have to press the accelerator initialy while starting the engine as the initial RPM while starting the engine is too low and the engine goes off if accelerator not given..

Some say that LPG kit cannot be fitted to 1.6..and no one suggests LPG for a 1.6...

All the techies out here please help me as iam in a confusion what had gone wrong with my car...should i remove the LPG kit or is it the sensor which causes the problem.. i still feel that the sensor must have damaged during the LPG fitment as the air intake pipe had to be removed and the mixture had to be fitted and refitted again(had to change the mixture many times as it dint make up with the 100bhp engine and atlast had fitted the mixture for a lancer petrol engine) as there is no specific mixture for a 1.6...

Guys please do help me on this....And is it true that an LPG kit cannot be fitted into a 1.6(disaster for me if it is a yes)...has anyone over here fitted in an LPG for their 1.6..if yes please do share in your views in here as it would be a great help for me..

There is nothing like LPG cannot be fitted on 1.6L engine. People have even done on cars like Optra and NHC. I sense that the installer has fixed the wrong kit on your car possibly the one used on 1.2L.

Can you check the rating of the Vaporiser? I am not exactly sure of the rating, but it has be higher than the one used for less powered cars.

Which brand you are using for 1.6 ?
