CHECK ENGINE CODE 25 and 26 NEED HELP?
My check engine light has been ramdomly going on and off for the past couple months. The codes are Running lean indicator and running rich. I have 120,000 miles and i changed the oxygen sensor with a OEM Toyota sensor at 97,000 miles due to the same codes. Now what could be the problem and how can I go about checking other sensors? Does anyone know a link to a factory service manual? My haynes manual gives about 6 different possible causes but I not sure on how to go about checking them. I am very mechanically inclined however these computerized things drive me crazy. LOL. Thanks in advance.

Have you pulled your battery cable to clear the codes??? Make sure you have cleared them so you don't look at an old code as this can be confusing.
the oxygen sensor and the Mass Air Flow Sensor (MAF) are common suspect items.
