I don't have a manual, so I need to know what the ECT or ETC button does. also have a slow trottle responce, any help whould be great.

 

ect power the button drives the truck at a higher gear than anticipated I believe it is for towing up hill, but don't ride in it normally it's not good for the truck and for the manual buy one off ebay or a chilton or haynes even from autozone if you dont' want to leave the house. hope it helps later.

 

What year is your 4Runner? T

Check out the website listed above. It has a troubleshooting guide for Toyota ECT's, which is an acronym for Electronically Controlled Transmission, as opposed to a hydraulically controlled transmission.
