question about a small hole in the t/b
question about a small hole in the t/b i was wondering what the small hole in the throttle body is it looks like someone jb welded the hole shut then drilled it to size... should this be a concern??? the car high idles a little bit and im suspicous of this being the problem can i just weld the hole shut? does it need to be open?
hole is there so that the car can idle with the tb closed. Think about it, if you had the tb completely closed off, no air would get into the engine=no going to start or stay idling. Sometimes people open up the hole bigger if they install a bigger cam and are having problems with idling issues (better to tune for it but its the "cheap" method). You can however either install a new tb with the proper sized hole or weld it shut and re-drill a new one. JB is a bad idea because if it flakes off, guess where its going...
the car has a tune on it right now but if the tuner doesnt know about the hole in the tb then i guess i have another issue??? i love it when people rig stuff together i dont know why people do that
