    I think that's what everyone was waiting to hear. That's the norm when reconnecting a battery. Runs rough for a bit then the pcm adjusts everything and life is good. Maybe the battery terminal connection had some dirt causing the electrical path to be weak.

    So can we file this in the "problems solved" cabinet now?

    Bad grounds can cause all sorts of wierd stuff . lf there's build up in the throttle body it will cause erratic idle also try cleaning the throttle body and the iac valve
    If speed kill's do brakes give life ?

    unplug the tps, and then after three start cycles plug it back in
    The car will idle without the tps being plugged in

    worked for me
