  1. Intermittently high idle speed, 1992 4.0 V6.

    A little feedback if it helps anyone else. The issue was intermittent and returned worse than before and was very frustrating. I threw in the towel and brought it to a mechanic. He replaced the throttle position sensor and that fixed the problem. I didn't even see a TPS in the shop manual. Oh...

    Thank you for your time and expertise. I'll change the sensor if this has not fixed it; you were a big help have a great day. Bill

    https://www.amazon.com/photos/shared/ZzOFX4rBTsigITXWBT3L1A.i5lStEhW0GSfKpIpDHSaQp This is the end of the hose that I am pretty sure was supposed to be on the mystery part.

    Great, now I have to figure out how to attach pictures LOL
  12. Intermittently high idle speed, 1992 4.0 V6.

    OK Ron, here’s an update. Your information has been very helpful. I went out to the truck, and started looking around for the sensor. Before I found the sensor, I found a disconnected vacuum hose! I don’t know if this was there all the time, or if it’s something also that just happened...
  13. Intermittently high idle speed, 1992 4.0 V6.

    Again Ron, I am grateful for your help. I think you will help me get to the bottom of this. I did change the PCV valve sometime ago, and it makes the normal rattling sound when I shake it but it is cheap maybe I could try another one. I didn’t ask the mechanic to change the thermostat, I agree...
  14. Intermittently high idle speed, 1992 4.0 V6.

    Even adjusting my expectations for how low the idle should be, it still occasionally stays too fast, 1000 RPM in gear. 1500 or so in neutral. But again, unpredictable.
  15. Intermittently high idle speed, 1992 4.0 V6.

    Thank you for the thoughtful detailed and helpful reply! This brings up another thing I forgot to mention, at some point my mechanic replaced my thermostat with one that runs the engine at a cooler temperature. If I recall though, I had the idle issue before that change. Could that be part of...
  16. Intermittently high idle speed, 1992 4.0 V6.

    Good morning friends. I’ve been a member this forum for a very long time but have not posted in a while. I need some help with my beautiful 1992 4.0 V6 four-wheel-drive automatic transmission Ranger. It has 112,000 miles, and does not get used very much. I have other vehicles that I use most...

    Good afternoon gentlemen. Thank you in advance for your help. I have been a member of this form for many years, but have not been active. I have a 1992 ranger 4.0 V6 four-wheel-drive.

  18. Seat recliner failure

    Hello guys, thanks in advance for your help. 1992 Ranger STX Extended Cab 4X4 4.0V6 A4LD 106,000 miles. The ratchet that reclines the seat on the drivers side is failing, and the passenger side is not far behind. If I lean back too hard the ratchet slips and the seat reclines. Annoying and...
  19. How to replace directional indicator bulb?

    I did a search and did not find the info I was looking for. The shop manual I have was not much help either. I need to replace the right turn signal indicator bulb (the green arrow on the instrument panel) and need to know how. Do I have to pull the dash apart? Any idea off hand which bulb I...
  20. Stuck in Four Wheel Drive

    Need some help fellas. My Haynes manual does not seem to address this. I have a 1992 SLT 4X4 A4LD 4.0 with a BW 1354 (I think). It's the one with the electric transfer case motor. 97,000 miles. It's been in 4WD the past week due to lots of snow, and it warmed up and I tried pushing the button...
