sam0044 54 Posted February 12, 2016 Hey all, so lately my 86 xf falcon has begun stalling it is a 3 speed auto carby. The stalling happens irregularly. Sometimes I can't even idle without stalling other times it's when I put it in gear, it has an auto Choke as well any help would be greatly appreciated!<br /><br /><br />Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
FOMOCOHO 882 Posted February 12, 2016 Vacuum leak - Option A Not sure on the details of XF vacuum lines but check for leaks in all. At that age vacuum hoses could be cracked or plastic joiners failing. If there is a leak it can really affect the idle & running of a crossy sometimes. 1 Outback Jack reacted to this Share this post Link to post Share on other sites
FOMOCOHO 882 Posted February 12, 2016 Option B - if you can't find the leak, remove engine & replace with clevo. 2 revhead and user272 reacted to this Share this post Link to post Share on other sites
FOMOCOHO 882 Posted February 12, 2016 Fuel starvation It could also be the fuel filter. Probably find it about half way along on the passenger side behind the sill. Locate, remove & replace. Share this post Link to post Share on other sites
SPArKy_Dave 8,881 Posted February 12, 2016 From factory, XF's only have a filter sock on the end of the tank pickup, and a tiny gauze sleeve in the carby behind the hard-line inlet fitting. Anything else, is either dealer fitted, or aftermarket. (not sure on EFI crossflows) 1 FOMOCOHO reacted to this Share this post Link to post Share on other sites
tpak addict 1,909 Posted February 12, 2016 EFI have a fuel filter on passenger side under front passenger door or thereabouts 1 FOMOCOHO reacted to this Share this post Link to post Share on other sites
Jiminy Kriket 133 Posted February 12, 2016 what revs does it idle at? Does it idle smooth or is it rough as guts? When my carb setup used to play up like that it was usually the brass plug/corrector jet on the passengers side of the carb fouled up with crap from somewhere. I'd be checking that first. While you are in the carb area, as dave said check the filter on the fuel in side of the carb. And also look for split or loose vacuum connections on the carb itself. Always a bother those things. 2 Outback Jack and FOMOCOHO reacted to this Share this post Link to post Share on other sites
