i have a throttle body that has no tps ....i know that it i comes with 2 rivits that hold it on but can i use a screw or bolt and if so what size ?

 

mine is screwed on not sure about the size, try looking for a write up (or google it) on replacing the tps it might yield the thread pitch. oh and when you search keep in mind that all honda TPS's are the same

 

they are not rivets. they are a screw with no head on them. you can cut a slot in it, and use a flat-head screw driver. here, read this, this is where i found this info. good info too, maybe it should be included in an faq on this site?

just take the TB off and bring it to the hardware store, it shouldn't take too long
