    confused Emissions light and tickover

    I purchased a low milage 3.2 Elite a few weeks ago and I feel that the tickover at 500rpm is very slow. If I leave the engine ticking over for more than about 30 seconds, the emissions light flashes on the dashboard and the engine starts missfiring.
    I have changed the sparkplugs and I know that the previous owner replaced 1 of the coilpacks.
    If I control the tickover with the accelerator at standstill by increasing the rpm's to @750, the light does not come on and the missfire doesn't occur.
    Has anyone else had this problem?
    Does anyone have a resolution?
