    1994 ford explorer, idle fluxuates
    At times my car is good but at times it starts to behave bad. Ihave changed the fuel pump and filter. Cleaned the injectors. I put a new o2 sensor.Its rpm is at 500 and then 1000 and back or lower to the point that it shuts off. What else could be giving me that problem?

    . Ensure spark plugs (Motorcraft) and spark plug wires are relatively new.
    . Check/replace Ignition Control Module and coil pack.
    . Check for codes.

    . Check for vacuum leaks.
    . Check/clean Idle Air Control Valve (IACV) and hoses--I use brake cleaner.
    . Clean throttle body with Throttle Body Cleaner approved for teflon coated throttle valves; e.g. Valvoline Throttle Body Cleaner or 3M's Throttle Body Cleaner.

    If the problem persists, read the link below for ideas, even though it's primarily written for Hondas:
