1990 Toyota Land Cruiser 4.0L Excessive Emissions, Poor Idle Quality, Hesitation, Misfire, high HC, low CO
Two possible problems: major vac leak causing 4000HC, CO .02% and lean running caused by sticking injectors. Came in running 3500 ppm HC, .02 CO, then cleared itself up after I pinched off various vac sources. Will run OK at idle but lean.
