broken stud on the throttle Body
OH boy....Like my project wasn't big enough without this little wrinkle. Today the rear lower stud on my TB broke off while I was tightening the bolt to hold on my greddy elbow. When it happened I immediately decided that was it for the day and packed it in so I don't know where it broke off but I am assumming that it is flush with the side of the TB. I am posting this to see if anybody has any ideas on how I should go about fixing this. I thought I should first try to get the stud out with an easy out. The stud is very thin and I have little confidence that, that will work. If it does, great just put in a new stud...if not, which is what I expect I then thought I would have to drill the stud out and either retap the hole or just see if I can run a regular bolt through the TB and elbow. Fortunately there is a hole where the back of the stud is so I would be able to get a regular bolt through there as long as I ground off a bit of the bolt head to let it fit in that spot (you'd probably need to be looking at the TB to know what I was talking about) Any ideas other than what I mentioned would be great. Thanks

I won't let go
I had the same problem on mine. Lower front though. It was just long enough to get the nut on, but not be able to tighten it. I had not noticed any leaks or anything else for that matter. BUT, see above...
Good luck.

I haven't heard of a helicoil before...is that where you take the TB and spin around then throw it as far as you can?? haha hopefully this won't come to that. Seriously though what is a helicoil?

oh, one thing you can do is just weld in a new stud there if your good with a tig or super good with a mig. just make sure you got good penetration and grind down the stud on the sides a bit before welding it on

Most places like Autozone have them. You just need the pitch size to purchase the correct kit.

I did the same thing a while back.
I was able to dremel a line into the bolt (that had snapped do to over torqueing) and then simply backed it out with a flathead screwdriver.

What is the part number of the two lower studs on the throttle body?
Mazda put a reman in my car last summer, and last weekend I took the intake elbow off to figure out their wiring job on my coolant level sensor and found that both the bottom two studs on the throttle body were gone. They used bolts to hold the elbow on, but the front bottom one doesn't really garb (tighten). Either it isn't long enough or the threads are stripped. I will have to check this out when it warms up here.
I am also getting a vacuum reading of 14-15"Hg at idle and am thinking that the elbow/throttle body connection might be the cause. I have 500 miles on the engine so shouldn’t I be getting around 18"Hg at idle?
