hey every one

I have a 98 dodge ram 5.2l that runs lpg/fuel
when I am driving on fuel it starts to shake around 60/80 km but when I turn it over to lpg it will run sweet as. I got told number 5 was playing up. it has new plugs and have tested all the injectors and the seem good, so I am lost at this point any help would be nice

Shake is the physical manifestation of the miss. That's probably right around where O/D engages, right?

Since it runs good on LPG, but, not on gas, I would be real tempted to replace the injectors.....

How many miles on the truck?

If the injector ohm test well (11-15ohms) and you can hear a click listening with a screwdriver or stethoscope, you can also try replacing the injector filter screens. www.osidetiger.com has a kit for less than $20

the truck has done 110 000 miles, I have tested the injectors and they all were good, putting new seals on them to night and put it back to gether

ok thank you I will check that when I get it together again
