Sounds like you installed the plate the wrong way around. Either upside down or wrong side around.

The blade is designed to fit the bore very close.

Re: Throttle body blade wont close all the way

Ok so i sprayed an entire can of throttle body cleaner in it and it looks almost polished inside. i ended up taking the trottle body off and got the blade in put it all back together but it still idles at 1k. Is that just he throttle body cleaner going through the system or something else. Oh and btw i took the one sensor one sensor that reads from the inside of the throttle body off and cleaned it too. Its not the one on the shaft

Re: Throttle body blade wont close all the way

The one off the shaft is the Idle Air Control Valve, cleaning it will take it under a minute to adjust its self. When you put the blade back in open and close the throttle a couple of times before installing the screws to make sure its centered. Sometimes after cleaning the TB you may have to adjust the throttle stop screw if it sticking when you press the gas pedal adjust the screw in a 1/16 to 1/8 of a turn.

If the throttle plate does not seal or if those rivets holding the diffuser have come out it will idle high.

If the rivets are no longer there you can put some in with a pop rivet gun. Or go to a wrecker and get another throttle plate and re do the mod by cutting off the half moon only this time.
Yes it will idle high, there should only be the center hole. Too much air is getting in while the TPS reads zero.

It sounds like it is not in perfectly. There is very little if any room for tolerance if its not in perfectly. Move it around a bit and open and close the blade with the throttle cable. Make sure there is no carbon on the throat of the throttle body. Dont mess with the rivets.
