Slight Missfire/coughing On Idle And Dead Surge On Boost

[Mulisha]

Hi guys

I have a Nissan Patrol and when i hit boost it will spool quickly like normal for about .5sec and then just die complety like a huge of nothing in a way. Then when you let it idle it will be idling and with constant missing and coughs and stuff. When u give it a quick rev off idle has a miss also.

I changed the spark plugs this afternoon with no gain at all.

I closed up the garage and turned the lights off and i couldn't see one like spark from any of the leads.

Then took No.1 lead off and put a screwdriver in it and and put it against some metal and it has a nice blue spark.

I really have no idea what to look at next ..

car runs striaght LPG thru Gas Research and has a Tb42 motor which is a 4.2L straight six.

Not sure if it's fuel or elec or motor or turbo i got no idea.

Thanks for any help guys/girls!

Rick.

hey mate,

if u put ur foot down and it gets to 0 boost, does the car just start to splutter and not go anywhere? also when it idles does it konk out? and one more thing...when u rev it...does t shit load of fuel smoke come out the exahust?

coz i had these issues, i changed the air flow meter and it was perfect. im not sure what anyone else thinks..but since they havene replied, then giv it a go! its got to be it.

hope this helps
