hi all i have an idling problem on lpg only, doesnt happen all the time only now and then, system is a landi controller v2, only 8 mths old runs good, every now and then when i pull up, the idles drop right down and goes to stall and i can smell the gas like it might be getting to much or not enough, then i can turn engine off and restart and 90% of the time it will be ok, the car will run fine for ages and then all of a sudden it will do this, it done it today when i got home from work on my front yard, idles dropped and ran rough, i given up with the installer hes a joke so im looking for a place that might be able to help me,im in quakers hill nsw, the system came from apollo gas but was not installed by them, the car idles great on petrol and never has a problem, awhile ago it done this and we replaced throttle body and idle control units, also when i do 60k plus on a trip at the same revs it seems to jerk back and forward only on gas not petrol but not all the time, like its also starving for gas, im starting to believe maybe a faulty part or the installer didnt tune computer properly, so if anyone with knowledge can help please pm me regards chris

Also the O2 sensors could be on the way out. These are really important for your closed loop controller.
