After Getting my new ute lowered yesterday the gas has gone up the creek..... they would have had to taken the converter off the strut tower to put the new struts in, anyways it hesitates when u take off when u put ur foot down there is nothing thenit just kicks in and when i had it on cruise the revs were jumping up and down, and if you come off acceleration and brake the revs drop very low and it stalled a couple of time at round abouts and stuff..... im thinking its got something to do with the wiring cause i dont think they dissconnected the gas lines and its fine on petrol.. could they have the wires on the soleniod hooked up wrong???? any help wpuld be great. i am going back down there this morn to see what was taken off...

The convertor might be full of muck and need a drain out??

Thier could be some leaks in the intake as well, mabe see if you can find any and get em patched up. Otherwise the only thing i can think of would be the converter or something to do with the Throttle Position sensor i know i had to reset mine and calibrate it and it made the LPG work a lot better and i had similar problems to what your having.

there is usually a hose that goes from bottom of airbox/intake scoope to the converter this controls the amount of gas required sounds like they did not put this on properly or tore the hose somewhere.
