She was getn a full vinyl wrap and my husband passed in the process. it took me 3 months to finish & I connected battery & chngd serpentine belt. Started her up & started w/no problem but idled very high (RPM in 2,000 to 3,000) 4 abt 5 to 10 sec then wld idle dn to normal i left running for abt 30 minute to run that old gas so fill the tank up. In 1st &2nd idled very high (even when i didnt give it gas) until abt 45 mph To downshift it wld idle hi in th 3s until i came to a complete stop and it wld idle for abt 5 sec and go to normal. I took off and cleaned the throttle body but it still is doing the same thing? Any ideas of what the problem is?

Vacuum leak?
