Hi, my VX just started to idle rough in park over the last week. In gear(under a small load) it idles just fine but as soon as i put in park the idle comes way down to 500rpm or so and shoots up to 1500 and then comes down to normal idle and runs rough.. seems to be missing.

Has anyone had a similar problem? I suppose it could be a small vacuum leak and under load it gets more fuel to smooth it out? Only guessing as it seems some had intake leaks. could it be the intake leaking?

thanks
