I have a 93 blazer S-10 giving me a diag code 44 (o_2 sensor LEAN CONDITION). i have about 5-600 miles on a brand new 0_2 sensor. can this lean condition be an air cleaner problem (new a/c put in with 0_2). i very seldom drive in a dusty condition (gravel road once per month the last 2 months). may it be a MAP sensor problem--if so, wouldn't it code MAP? anybody run across a similar condition--THANX
