    engine check light finally came on.i work at advance auto parts and we do free check engine light scans.i have the 4.0 ohv and it starting to idling very low(below 1k).i scanned it and i got 2 trouble codes. p1507 idle air control speed low and p0133 oxygen sensor bank1 sensor 1.i know this is a upsteam sensor but is it driverside or passenger side? and what should i replace for the idle air code? dont wanna replace the idle air control solenoid if it may be the result of another problem.

    Heat up the threads near the sensor locktite is usually used and the sensors tend to get frozen in place. If need be Cut the wire and use a long socket on a torque wrench to remove it.
