3.9 stalling
Posted: Thu Jan 03, 2013 11:59 am
hi team,
i recently installed a 3.9 into my old army stage 1
so far i am pretty happy except for an annoying problem.
it idles ok but when pulling up to a stop it often (but not always) stalls.
i have downloaded a disco1 manual off the net which talks about the vehicle speed sensor which disengages the idle air control valve when the vehicle is moving
as mine has no speed sensor as it was mated up to the original gearbox (lt95) could this be the problem??
could the ecu be getting screwed up with no input from the speed sensor?
i have cleaned the iac valve, put in new plugs, checked and adjusted timing, checked maf sensor for any buildup of dirt etc, checked for air leaks around intake, cleaned rocker breather, checked compression is ok
