Adjust the idle screw......should be roughly 750 -900rpm when warm

I'm his brother in-law. I did adjust the idel screw, maybe I need to do it a ton more, it's idling at around 1700. I also replaced a good amount of the vacuum lines. Anything else to help us out?

check timing

Check the timing and adjust the idle screw see if that works. I changed my o2 sensor and thermostat. My o2 sensor was bad and my thermostat was no good once i changed both and adjusted the idle screw she has been fine.

I had the same problem...I turned my idle screw all the way in..and my motor still idled at 1400 rpms...to high...

listen...where the throttle cable hooks to the throttle wheel , look under that...there is a stud with a nut on it...and one end of the stud has the nut..the other end of the stud hit this plastic boot looking thing....

I adjusted that nut and it fixed my hi idle problem...the nut is very difficult to get to...but it can be done.

Check your TPS. Roger (4Crawler) has a how to on his website.

mine had an issue similar to this and i was able to fix it with a new throttle body and now it seems to work just fine idling right around 700-800rpms

I am also having the same problem. When you say check the TPS, what'd should I be looking for?

Should I look for a drop out? High resistance? Low resistance?

Thanks

Hi there, hoping to revive this forum as I'm experiencing similar problems with my 1991 3.0 V6 3vZe.

Just seeing if the issues were eventually resolved with your T4R in order to start the process with mine. I'd rather not throw parts at this problem to keep the cost down, if at all possible.

I live in a winter climate and don't have a workshop therefore I'm paying to have the work done at a local garage. Truck is in good working order, has
130 000 KM's (80 000 miles or so). I'm the second owner but the truck was very well maintained by the previous. truck was running impeccably until about 1 year ago when the fan clutch went, it has been replaced but since then I've noticed gas mileage has become horrible.

Truck is idling at about 1200 rpm after warmed up, and guzzles through a full tank of gas of roughly 60L in 320 KM's! (15 gal in 200 miles).

Upon first inspection the mechanic said that temperature was checked on the hoses and heat is good so he does not suspect the thermostat is the issue. also the throttle body was inspected and looks clean and in good working order. throttle cable checked as well and no issue. Mechanic said the adjustment screw is capped from the factory and he does not think removing the cap and making adjustments is a good idea.

he said the next step might be replacing the throttle body but finding a new one is not easy and buying used doesn't inspire much confidence as most of the ones in eastern Canada are rusted to shit.. wondering what to do next?

Truck is in excellent shape and would love to keep it running if possible
