Hi, I have a 97 Wrangler 2.5 and recently when I stop or slow down suddenly the rpm will fall below idle. It drops to about 500 rpm. I have read that it could have something to do with the exhaust but I don't want to go tearing apart the engine to find nothing. Looking for a quick fix because this car is my daily driver! Also note the temperature outside has been around 30-40 degrees, not sure if that could be affecting it as well. As it stands I'm not super worried about it because it doesn't seem to affect the overall performance of the vehicle. Any thoughts? Thanks.
