hiten55 Posted January 7, 2008 Share Posted January 7, 2008 its burning of excess fuel in the exhaust or something. sounds like you need a tune up as always, i could be wrong Quote Link to comment Share on other sites More sharing options...
wilkorangerover Posted January 7, 2008 Author Share Posted January 7, 2008 could it be with it not being used for a while, and cold? Quote Link to comment Share on other sites More sharing options...
suprattgaz Posted January 7, 2008 Share Posted January 7, 2008 "You got a nasty hole in your fuel MAP" Seriously some crap stuck in your spark plugs or injectors. Quote Link to comment Share on other sites More sharing options...
hiten55 Posted January 7, 2008 Share Posted January 7, 2008 see, told you i was wrong Quote Link to comment Share on other sites More sharing options...
suprattgaz Posted January 7, 2008 Share Posted January 7, 2008 Do you have a BOV, they can create popping too. Don't forget it is f'ing cold, and the air density is very different creating a differential in your fuel, air mixture. Mine does it in the cold sometimes:cool: Quote Link to comment Share on other sites More sharing options...
wilkorangerover Posted January 7, 2008 Author Share Posted January 7, 2008 i would think spark plugs should be ok as they were only changed a few months ago.... injectors?? how do you clean them? injector cleaner?? Quote Link to comment Share on other sites More sharing options...

Thought it over again, see thread above yours;) Anyhows in answer to your above a seriously good thrashing normally blows the sh*t out, unless is is more serious (coil packs etc) Quote Link to comment Share on other sites More sharing options...
