got a 2.3 88 auto,the issue is once hot and in park it idels at 1300: starts cold first try idles at 700rpm, in drive at 1000,but once it warms up and placed park its at 1300.
Can someone help figure this out?
looks like an vacume leak or possibley an idle air control sensor. could be many things, take to dealer to diagnose but start with these.
