    Problems now: Main issue now is when the AC is activated, the idle fluctuates and when the AC is turned off, it dogs the system. Idle will remain low. I was having random idle issues with no AC but was fixed.

    Fixes:
    - Ignition Starter Switch
    - Cleaned Throttle Body and Plenum
    - EGR Valve
    - Cleaned MAF
    - IAC Valve
    - Fuel Filter
    - Air Filter
    - Battery
    - Alternator
    - Serpentine Belt
    - Spark Plugs
    - Battery Terminals
    - No Vacuum Leaks(that could be found)
    - I hope I listed all

    I have spent some time working on it. Random idle fixed. Now need to know about the AC. Could it be low freon or bad compressor?

    What issue are you having now that the random idle is fixed? It could be the clutch going bad. I don't think it is low refrigerant sine the compressor would cycle on and off in short intervals.
