rpm's bouncing! help!!!!!

[shocar4]

hey guys today i cleaned my throttle body with cleaner real good and it looks really nice now, but when i am going down the road and shift to neutral, my rpms bounce from 1300 to 700 like crazy...what do you think is the problem? i checked all my connections and everything looks good. i reset the battery and i will see how it is in the morning....do you guys have any ideas what the deal is?

update!!! When i started the car up this morning i was idling at 1900 rpms.....which is higher than usual, but then it was like the throttle was sticking when i let off the gas (while going down the road) and after it warmed up, it started bouncing again while in neutral and rolling! but at a stop light it idles real high 1900rpms! could it be that my air idle control got mucked up during the cleaning process? where is that located on the throttle body?

How many miles do you have on the car? tune up maybe?

Just have it diagnosed.

it has to have something to do with cleaning the tb lastnight, because it never did it unitl after i cleaned it....where is the idle control located?

Your IAC valve is not working right. Probably got mucked up during the TB cleaning process, take it apart and clean it and make sure it moves freely. It could be what causes a MIL.

update!!! well i recleaned the throttle body and all the components around it lastnight and it seemed to solve the problem. i did have to set my idle a little different, but i drove 40 miles this morning and it seemed just perfect...knock on wood!
