ok, here goes,
3.0l with lpg(dissconnected). from 1st start up cold or hot it runs very lumpy, try to drive off & it will cough & splutter, no power for maybe about 5-10 seconds then it will rev as normal. only does it from startup. drives normally after.
ive changed the maf, the tps, the icv. even throttle body & plenumn. dont seem to able to find any vac leaks.
now, ive noticed that its worse when the sai pump is running.
do we have any ideas chaps. oh, no codes are shown or management lights come on at all.
regards, jon.
baffled.
