    Are you 100% sure you've got your plug wires in the right order?

    OK, tested the O2 sensor and coolant temp sensor, and they both tested fine. cleaned my ICV. Still does it, and to add a twist, seems to idle better when i disconnect the harness from the coolant temp sensor... and its more of a wavering idle rather than a stumbling idle. Revs up and drives great. Throttle response SUCKS. If you give it a quick tap, it almost stalls. What is going on???

    what the hell, when did I become some kind of tech guru outside of electrical shit?

    Srsly, if it runs OK cold, but stumbles when warm, I would check the O2 sensor first, then clean the ICV, maybe test the coolant temp sensor.

    GL!

    adjust your throttle and afm. masure all spark plugs fire. go over everything you did.

    Would my throttle/afm need adjusting as a result of what I did? I dont see how anything I replaced would affect these components....

    $500 in parts- now have stumbling issue

    Decided to do some preventitive maintenance on my perfectly running 88 325i cabby, so did the following:

    Oil pan gasket (shortcut method used)
    valve cover gasket
    camshaft seal and o-ring
    timing belt
    reference sensor
    coolant temp sensor
    wires
    cap
    rotor
    belts
    hoses
    water pump
    plugs
    coolant flush

    I got everything at Bavarian. I double checked all my electrical connections and cleaned with contact cleaner.

    SO, when it started, it ran pretty good cold, but once it started warming up, started stumbling at idle. I can rev it up and it sounds good.

    Don't suspect ICV since it ran fine before.
    Check engine light was on right after finishing installing the parts, but disconnected battery and reconnected and it was not on after that.

    What the flying f***.
