Hello, I just pulled the codes off my 92 trooper 3.2 SOHC, and I got a code 14(Coolant Temperature Sensor Circuit) and a code 24( Vehicle Speed Sensor (VSS) circuit). I already assumed I needed a new vehicle speed sensor, because my speedometer works intermittently. The reason I checked the codes is because my engine idles vey high when I first start it up, whether it is cold or hot. Then after about 5 minutes, the check engine light comes on, and the engine settles down to a normal idle. I was just wondering if anyone could tell me what to check, or has had this problem. I recall on my '88 Troop the coolant temp sensor played a part in the idle speed if it got too hot or something. Any help would be appreciated.
