Taking out of park makes vehicle cut off.
When I turn my van on I have to hit the gas for it to
start. When I take it out of park the van cutts off
unless I keep my foot on the gas. It stutters if you
try to drive it. Someone has told me it could be a
catylitic converter. But would like other
Catilac converter would be one,but next check your fuel pressure,may be bad fuel pump or filter.
You may just need a tuneup. The IAC may be going bad.
