    Buying cheap 99 explorer for cheap and few things I'm worried about. First off rear two doors are stuck which shouldn't be hard just a pain. Second it there's no smoke coming from exhaust thank god but needs a tune up. What is involved in tune up for it?
    Coolant flush
    Oil change
    Air filter
    Spark plugs
    Cool pack
    Clean tb.

    How much blow-by is coming from open
    oil fill cap when motor is idling?

    Consider cleaning the MAF with MAF only
    cleaner, be sure let air dry 15 minutes before starting engine,
    also cleaning the IAC.
    Do the spark plug wires need changing?

    You can see and feel pressure coming
    out of the open oil fill cap.

    This means more than usual compression is coming past the
    rings and indicates high wear in one or more of the cylinders.

    Another indication of excessive wear or broken oil rings
    is oiled up spark plugs weather it be a single plug, several or all.

    You can stop by a Midas and they'll do a bumper-bumper check for $100 also...

    I'm assuming it's a 4.0. I know they need timing chains done around the 150k mark so keep that in mind. Cleaning the Maf is a must as well as replacing the intake gaskets, that will cause some hesitation too.
