Check the various throttle controlls. there should be a grey box with an unusual nut on it. have a car guy look it over. the vehicle will have a cold-start high idle for a few minutes before selling down if it's a V6.

4runner idle high when cold after warm up it idle 1200 rpm shot down engine after fuw min. restarting the engine the idle to low?

it seems that the auto choke setting is maybe wrong or there is a problem with engine management, or a worn part which is sticking.

when cold, the engine should be higher as the choke will be on but a warm up idle of 1200 seem a bit high i would expect around 800 and then on restart if the engine is warm then the choke should be off but the idle being too low indicates one of the above.

93 toyota 4runner speedometer not working

ive had the same problem,, but mine also has no shift pattern sometimes. sometimes i can be idling and my speedo is all over the charts. three people told me to replace the speed sensor. it had one 12mm bolt attaching it, but it is in a stupid spot tucked behined the mounting bracket on the left side with two wiress coming from it. I just held the tranny up and dropped the whole cross meber. but I dont think that is necessary. you can most likely get at it with an open end wrench. you gotta have faith!! burns-

Hi, I have a 1994 4runner and I want to turn the idel down , how would I do this thanks so much. v6 3.0

here is the same disappointing news i got.. with the 3.0 you can adjust the idle .. which is good and bad! good being it will adjust itself,, bad being if its idling a lil high you cant turn it down some...most common reason it will idle high is due to a bad sensor or a vac, line leak.

in my case mine was idling about 1200 to 1500 rpms and huge power loss,,, i just dropped heads off today at cylinder head shop with burnt valve lol
