Engine revs when it’s hot.
On hot days if I get out of my car and get back in while the engine is still hot the car will start but it revs between 1500 and 2000 rpm. It just goes up to 2000 and drops back down to 1500 over and over. Any ideas what could cause this? It is a 92 SC400 with 102,000 miles.
