What was wrong with your OEM unit? Are you sure that is it sticking, or is it just a huge vacuum leak?

Did you replace the gasket, or make a new gasket for the TB to IM connection?

Did you port match you OEM Intake manifold to the throttle body?

Yea im absolutley sure its sticking even out of the box it was pretty sticky.

and yea it came with a set of gaskets.

I'm not sure what you mean by port match I just recently started to fix this civic and barley have a clue of what im doing.

I mostly have semi stupid friends and forums like this to help me hah.

Port matching is making the Intake Manifold opening match the size of the throttle body opening. Without doing that, installing a bigger throttle body is basically pointless. This can be done with a Dremel, however, I doubt the OEM intake manifold can be ported that big. Also, the Intake manifold must be removed from the vehicle when doing this.

OEM TB - OEM IM
o - o

Your new TB - OEM IM
O - o

You are still being restricted by the OEM intake manifold. You are only as "free flowing" as your most restrictive piece in the system. Make sense?

I am not sure how to help you with the after market TB, but if the OEM TB has oil and junk in it, that is your problem. Take come brake cleaner, spray it in there and clean everything out with an old toothbrush.

When you say "sticking", you can physically "feel" the pedal sticking and you have to push on it harder to "unstick" and rev up the motor, right?

Lastly, what brand TB did you buy? eBay is not a brand.

I really should have taken that into account when buying that was a pretty dumb move on my part haha.

and yea I have to rev up the engine to get it to unstick

and it says it was an integra GSR TB that was promised to fit a 96 ex but the actual piece that you wrap the throttle cable around was flipped so I actually had to take the stock TB peice and switch it so that it would fit properly

That being said though it stuck even when I pulled it right out of the box when the Ups guy handed it to me.

Well, it is not an OEM GSR TB if it is actually 68mm. GSR's have a 60mm TB from stock. I just installed one on my H22.

Is it brand new? What brand is it? Basically any D/B/H/F throttle body will physically bolt up, but the throttle cable may need to be tweaked to operate correctly.

Clean out the OEM one like I mentioned, reinstall, and see if that changes anything.

Also, have you contacted the eBay seller?

Yea I kinda figured that they didn't come that big stock.

and thats all it said other than that there really is no brand, not on the throttle body or the box.

Thanks for the help and yes I did contact him and he said ill give you a 5% discount whenever you buy from me again well thats not gonna happen.

You could always request for a refund/return since the product does not work as described. If he refuses, file a PayPal claim stating that the item does not work as intended.

Ever get a chance to clean out the OEM unit and reinstall that?
