Thanks, I was wondering what the norm was for the 1.8 liter Toyota engine. Scangauge bounces between .16 -.17 & Ultragauge .14 -.15 on my '05 1ZZ-FE.
Does your idle gradually drop to a low point & then exhibit a slight roughness? I always assumed the mixture was intentionally leaned out by the computer to improve idle FE. I recently replaced my intake manifold gasket & idle quality/ low end torque have noticeably improved but still not a silky smooth idle like a Honda 4 banger. MPG seems better too-425 miles & still a little over 1/4 tank left.
