High Idle (2000-3000 rpm). Advice? Please?
 

I don't know a whole lot about my toyota yet. I've got a 94 sr5 with a 3vze v6. I recently swapped the engine for another one of the same kind. this may or may not have something to do with the problems im having. after it heats up it idles anywhere between 2000-3000 rpm. I've taken the intake off and cleaned it with carb cleaner, checked all the vacuum hoses. I drained the coolant and used a vacuum system to put it back in to make sure there was no air in it. My dad found the repair manual for his 88 pickup and told me it would help. I opened the daignostic box next to the fuse box and shorted out the E1 and T which is supposed to show the error code. the frequency and number of blinks i get for the code doesn't match any of the ones in the book. i don't know what else to do. any advice would be greatly appreciated.

I was having high idle issue the day before my timing chain wore through and dumped the water into the oil pan. Fix all of that, and the bolt broken off in the intake, jesssss. New timing chain, gears, thermo, all that stuff, was expecting that to have fixed the high idle. In short it did not. I thus repositioned the tps, waste of time, adjusted timing, no luck. Finally noticed that the screw on the throttle body that is "supposed" to be in cotact with the idle control valve was not. It just touched it but only when the little plunger was fully extended (Note it was NOT the throttle stop screw). I believe that what I am calling the IDCV is what other more knowledgeable folks on here are calling the "dashpot", someone correct me if I am wrong. So, I turned the idle control screw on top of the throttle body to center, now idling at about 2500, adjusted the screw to make "deeper" contact with the little plunger thingy, adjusted the idle screw on top of the throttle body to bring the idle down to 750. It has ran and idled slicker than snot on a doorknob ever since.
