OK guys. Ive had this problem for a while. My throttle does not want to close. When i drive the car and come to a complete stop my idle goes higher and higher. So after doing some searching and testing simple enough(I thought) my TB is not closing. After a drive it would be idling at about 1500k. While its idling there i can pop the hood and close the the TB manually and it goes back to regular. So today i took the TB apart and cleaned all the gunk carbon and dirt etc out of the TB. Everything seems to be fine. I even backed the fiav screw all the way down(the write up RRE or ams has for it) and it still idles retarded so i know its the TB. What can cause this? Is that nut thats on the spring of the TB in control of the TB plate returning to its normal position. The throttle cable to is also fine i adjusted it correctly and when the plate is not closed all the way at a stop the throttle cable has slack so i know its not the cable. What could it be? Does anyone know?
