i drive a 2000 nissan maxima SE automatic. lately when between 600 (idle) and 1200 rpm my car starts shaking/chugging/hesitating...whether in gear or in neutral. when it gets above about 2200 rpm the chugging goes away. the chugging is at its worst when i'm in 4th gear travelling around 37-40 mph and at 1300 rpm or so. when i turn on the a/c it gets worse...the chugging gets stronger and slower. when i turn off the a/c it gets weaker but chugs more rapidly. my car has lost a lot of power when in low rpm. any ideas of what's wrong? i looked up this problem on the net...all i could find is that it might be a problem with the mass airflow sensor being faulty or dirty.
i had this same problem in the beginning of the year...then it went away for 3-4 months in the summer...now it's back. wtf?
