Yes you are correct. Today I noticed the problem even after changing over to the gas (I mean after the changeing over was successfully completed) Seems that it goes away as I rev-up the engine few times. Since the engine is usually rev-up for the fuel switch over to take place (automatically) it was not aparent previously as I think. I went to the place where the gas conversion was done and they found no problem with their unit. I spoke to the Agent about the problem and they told that they don't recommend gas conversions for this vehicle and dont take such vehicles for engine repairs and I am about to ruin my engine!! . Any way I will do the engine tuneup and see. Will some injector cleaner additives help? Is it not good to run on gas as agent says?? What is meant by "Engine tune up" for EFI engines??? Thanks

thankx for swift response. I normally run on petrol until the engine heats up, around 1km or so before switch in to gas. The problem arises during that period but not while the cahnging over takes place. If I run my first kilometer on gas, same behavior is observed with loud backfiring.

Dear All I have recently purchsed a KR42 (2001) /GL with 117k in odo meter. It is fitted with a Lovato venturi type autogas unit and no records about how many kilometers it has been run on autogas since the conversion. It was imported to Sri Lanka at around 95k odo reading. My problem is, when it is driven around 1km in the morning (on petrol around 60kmph), it drops its pulling power and does not respond to the gas pedal. At this stage the engine shakes very badly and this cause the entire vehicle to shake and vibrate. If the fuel is changed over to gas it becomes fine. This happens almost every day. Please help me to come out of this problem. Am I running to a major engine repair? Thanks in advance
