Well i'm sure there is some way you can get that broken bolt out, but it would probably be easier to go to the junkyard and pickup a throttle body. No matter what you do the system will probably never run correctly with it detached like that.

 

agreed

 

I'm not sure what I'm looking at.

 

raptor, basically what he is showing is that one of the bolts for the egr valve broke off in the hole on the TB, therefore making it have this huge open space between the egr and tb.

 

thanks jake

 

i tried taking it out but it wouldent buge but ima try agin tomorow hopefully ill come out man those throttle body is expencive like 300 bucks used
