If short-term fuel trims are (for long period of time) very different from 0 (more than 10 .. 12 %) shortly after long-term fuel trims has been performed – it is a cause for concern, and situation has to be explored: something has made changes in engine operation. First off, are these fuel trim readings at idle or while driving?

It is actually pretty much like short-term fuel trim. Fuel trim is a calculation based on the O2 sensor readings from the sensors at position 1.

That’s long-term fuel trim (LTFT). Since fuel trim is an ongoing calculation, keeping one factor in the calculation constant makes it possible to return STFT to its normal range, enabling a faster and more accurate reaction to bigger changes in operating conditions, such as acceleration. Total fuel trim is an additive value: STFT+LTFT=Total Fuel Trim.

Long Term Fuel Trim (LTFT) -- The correction factor (percentage) being used by the fuel control system in both open and closed loop modes of operation. LTFT should typically be within plus or minus five. Positive LTFT numbers indicate the PCM is adding more fuel to compensate for a lean fuel condition. Scan data showed Short term maxed at 25% and long term at 0%. When engine RPM was raised (off idle) short term fuel trim dropped to a normal range. This indicated a vacuum leak. For a complete background and diagnostic information on fuel trim, see this Autologic technical article.
