Hey guys,
So I was getting the sticky throttle when the car was cold so I clean the throttle body it was disgusting. So the car cooled down and then I drove it, worked like a charm but now I noticed the idle is at 1100-1200 rpm, before it was at 900 rpm, is it possible the carbon build up was causing the idle to be lower? The car has a tune, is it possible the previous owner was having issues with idle due to the carbon build up so he tuned the idle higher to counteract the effects of the carbon build up?

No I haven't, if it is built into the tune that won't help correct.

I would disconnect the battery and re learn idle.
You now have adjusted/cleaned it up. eventually it will go back to normal, but disconnecting the battery will help it out faster.

I cleaned mine too when I did the throttle body seals. That was a mistake. It turns out the black "build up" on the throttle plate is there to seal it. If yo take the TB off again and shine a light with the plate closed you shouldn't see any light coming through. I bet yours will have light coming through which will cause the idle to be high. I had to buy a special coating to fix it. Search on here. There's a fix for it.Originally Posted by Frew

Sounds like you cleaned off the molybdenum dry lube from the throttle body. If the gap isn't that big the iac should be able to compensate and eventually the idle will work its way back to normal. You could also use evo scan and choose the idle screw button and set the idle screw on the throttle body to 800-900 from there and see how that goes. The best option would be to get some molybdenum dry lube and seal the plate back up. I bought a bottle of tomei throttle coat after making the same mistake you did by cleaning the throttle body and removing the dry lube seal.

I was going to get molykote 321 as well but for some reason it is prohibited for sale in my state (NY). I had to find a vendor who was able to get tomei throttle coat from japan. Took three weeks but finally got it.Originally Posted by 10isace

I will keep an eye on it, I had no idea that this even existed, if the idle doesnt return to normal I will recoat the inside of the throttle body with the molybdenum, thanks for the adviceOriginally Posted by rcheung

sorry to revive an old post but i am having idle problems and was thinking of cleaning my throttle body along with my maf sensor
i have both crc throttle body cleaner and maf sensor, although i was only planning on taking the i/c pipe off and spray the throttle body lightly and wipe with rag. but from the more i read i am starting to think it may not be worth cleaning at all :S ??
what did you guys end up doing ?

it will work, thats what cured my issue, I eventually took off the throttle body to do the seals and really cleaned it up. Throttle feels great at any engine temp now.

I just sea foam my ****. Never had a problem with idle or carbon build up.
