hey i have a 89 4runner v6, it only have about 50000 km on it. the problem dosnt happen all the time and mostly when i push on the brakes, but it revs up and down. also somtimes it revs up when i push in the clucth. ive check for vacum leaks and tested the brake boother, so i dont think its vacum. ive had some say its electial but i dont know were to start. i did have a mechanic friend unpluge the brake wiring and it did stop the reving up and down. the problem is, is im no mechanic and want my truck fixed. so any help would help thanxs
