Throttle Body plate not closing properly

[earthlyken]

Hello mga peepz, need help po regarding idling problem with my D15b manual, last saturday, nag pa change oil ako and spark plug then nag spray ako ng carb cleaner sa TB ko, then when i start the engine, all is normal then comes sunday when i use the car to drive my wife to the office, i notice na parang nag stuck yung idling niya from 1000 RPM to 1500RPM sa idle..i tried using my right foot to lift the gas pedal and the idling goes to normal..
pag uwi ko, tinangal ko yung airfilter to check the TB plate, malinis naman dahil nag sprat nako ng carb cleaner, then start ko ulit yung engine..now everytime i step on the gas pedal..ayun taas ng idle niya to 1500 and even reach 1800 RPM, pero pag pihit ko yung kabitan ng gas cable para mag close ng husto yung TB plate, bumabalik sa normal yung idle niya..
i'm running out of idea's po..i'm thinking that baka spring lang may sira..or maybe some other thing..kasi pag dirt lang, linis napo yung TB eh..yung plates lang talaga nakikita kong culprits kasi hinde siya nag close ng sagad..
any help will be greatly appreciated..

thanks for reading

Nangyari na rin yan sa akin bro. Suggest ko lang ipunta mo sa mechanic kc baka yung spring sa likod ang may problema. I don't now the name pero spring mechanism yun.

I hope this helps...

ang alam ko hinde naman talaga nagsasara ng fully close yung butterfly (plate) kasi para pumasok yung konting hangin. im not sure about yung engine specs pero ganito yung mechanical setting ng carb ko (civic EK) nung nagpalinis ako ng TB.

normally pag kinkalas yung TB as much as possible hinde dapat nagagalaw yung mga cable settings otherwise pag hinde naibalik ng tama pwede mag result sa ganito. yung sa akin matic pa kaya pati yung clutch cable naka attached sa throttle cable.

kung hinde ginalaw yung setting ng butterfly baka sa cable masyadong masikip or maluwag.
