Ok I just picked up a 2000 4runner. It currently has a high idle around 1700 rpm. I have changed collant temp sensor and checked all vacume lines. Also have checked throttle body for play. Still no success. Also the 4x4 light is blinking. I've checked front drive shaft and it seems front diff still locked in. Just wanting to know where to start with the 4x4. Also the cruse control don't set. The light comes on in the dash but doesn't actually set.

I don't know much about 4runners but on other makes/models, there is sometimes a second switch on the brake pedal that goes bad and won't let the cruise activate. also, sometimes its a single switch with two sensors and the cruise part goes bad.


do your tail lights come on when you hit the brakes?

Yes brake lights work fine. Cruze the the least of my worries though. High idle and 4x4 is the main ones I'm concerned about
