Hey I'm new. Recently bought a ranger and have been fixing it up. I have a weird problem with my truck. Worked fine when i bought it. Now when I start her up, when shes cold, she will idle at 1500rpm for a few minutes. When I start driving it will slowly work its way down to 800rpm at a stop over the course of 4-5 minute. Idle is slow to return to idle when i press the clutch. I was curious so I disconnected the TPS sensor. It started up revving to 1400 and dropped like a rock to 800rpm within seconds. Any ideas what I should check? I tested the resistance of the sensor. 0.6 ohms closed throttle, goes to about 3 wot. What do I check next? Why would the TPS affect the idle and slow return to idle like this? Any pointers are much appreciated. Thanks.
