Engine Performance problem
1995 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 230000 miles
I have a Jeep Cherokee 6cyl 95 Limited and have in the last 12 months had a LPG system fitted with a 45 litre petrol tank put in for dual fuel under the centre of teh car. I am having a small problem where the LPG fuel when driving along just cuts out, this also happens when braking at traffic lights, when drving I could be doing 60kmh with low revs and no change to speed or revs and it LPG cuts out, I have not nothed this with petrol but do not drive on petrol very often. I have noted that since the time of install of the LPG system the car has been quite heavy on gas with 20Litre to 100Km. The spark plugs have been changed with larger gap north american plugs (im in australia), the leads have been replaced with high volt/amp leads and the oxygen sensor has been replaced, the car has been tuned on a electronic machien at the car repaires and a MUTT plugged in for faults which I was told came back OK but slighly rich. Before I take it into the mechanic I would like to have so!
me idea of what could be wrong.
How often do LPG gas system need to be serviced? This appears to be a fuel delivery problem to me becuase after it stalls it is easier to flick the switch, start on petrol and drive for a few hundred meters and put back on gas, I have been able to start on gas after a stall but took 20 secs of cranking over, petrol starts relatively easily. This has only happend 7-8 times so far but always at steady speeds or slowing down speeds.
Thanks in advance for any help.
have the same problem?
