S90 Throttle Body Unstable Idling

[lanun]

Im using s90 on civic b20b but now getting prob on unstable idling n heard many user facing same problem bcs of vacum leak. Some said using 1gen S90 throttle body not facing idling issue. Some of bengkel said S90 itself prob ( most my frenz using on cibiv b series).

I was tried some method to get stable idling like TPS adjust, Iacv clean n etc. no check engine but still getting prob. 1 more wat the diff cooper butterfly wif crom butterfly? Any diff?

Try getting others brand as Skunk2 or Works (prefer coz cheap than skunk2). Any comment? Tq.

I used WORKS 70mm tb on my 93t b4 and i hate it because the fuel pedal feels so stiff, when u press the pedal, u only get ON and OFF, u cant gradually increase the pedal feel..The car wont move if u press the little too soft so when u press it harder, the car accelerate too much, if u stuck in bumper to bumper jam then u'll know wat i mean..Hate dat kind of feel..

As for chrome and copper butterfly, heard some said copper wont jam when it's hot, all my frens using S90 t/bodies nvr complain jam also and they been using it for years on the road and track as well..

I got it before (feel stiff), if jammed (or mount climbing) then u know la (im using Ogura he he so heavy de clutch). but u can adjust the butterfly to get smooth/soft pedal (i did before) but then u get idle prob. If butterfly tight properly then u didnt hav idle noticed but u will get hard to set pedal accel.

If there any Fake WOrks outside there? How to verify? How much the cost coz I c at leat has 2 model of works TB.

That because your TB is stick. U need to adjust the screw. 1 min can fix it

 

[kayour]

[jombiee]
