whats up guys. my auto timer is on a s13 sr20det blacktop, and its been on it for awhile with no issues. but just recently the air/fuel ratio will jump around between 3.0-4.30 constantly. normally when i start the car it starts out low about 1.80 then as it warms up it will get around 3.33 or so, and just fluctuate a few points or so. any help would be appreciated. thanks.
