I see the dealer diagnosing a problem as a throttle body failure all the time. It very rarely is. They don't "wear out", though they can need cleaning from time to time.
E-shaft sensor, a vacuum leak, a grounding problem, ignition problem, MAF cleaning, or O2 sensor failure are usually the actual problem when the dealer diagnoses the problem as a failing "throttle body".
Every once in a long while it actually is the throttle body, but I can remember less than 10 in 5 years of watching the forum. The throttle response with the engine off, so removing the intake and watching the actuation of the pedal with the actual throttle position sensor data from OBD2 should be enough to confirm that it's not the throttle body.
Please don't let them just throw parts at it.

I still don't see it. There is no lack of power in this thing and when it stalls the revs dip, go up, and then dip again but a compression test is a compression test! They're ringing tomorrow morning as I am just within warranty (runs out in April!!!!). I am not optimistic from what I see of Mazda fighting against the warranties :-(
The other pisser was that I asked them to see if they could free up the coolant sensor (it stopped working months ago when I was working on something else). I thought the coolant could actually be a little low.... It was, he pressure tested and the f***ing radiator has a leak. OEM $700, them to supply after market $315, locally sourced CTF (?) rad $150. Quite a crappy day really but could have been worse. Oh have looked at rad install diy - going to let the garage have that fun!
Anyway more news tomorrow. Please sacrifice first born to the warranty gods.
TIA

One last question for this thread have found several second hand throttle bodies from reclaimed cars at around $125 instead of the circa $720 I will be paying here (I am getting free labour).
So what does the team think about recovered throttle bodies???? Are they very delicate and so should not be used? I should say I found a couple of very reputable BIG recycling companies with 6 moth money back guarantees ... So what does anyone think?
TIA

As RIWWP says, rarely ever do they go bad so I would take the change at that price. I just found this thread and I'm still a little confused as to what was wrong with your original engine... Then again, something could have happened between your December compression test and now I suppose.
Anyway, good luck! And you life in freaking Hawaii... things could be worse!

They did a "hot" compression test which failed. As everyone says the throttle body failure is unlikely so I will double check with them.
Keep warm :-0

If we could just find somewhere in the middle! About to go to the beach (maybe) where it will be too damn hot for words :-(

Damn both throttle bodies I have found have around 130,000 miles on them. I presume that usage does effect these babies. There was one with lower mileage but that has gone and I have failed to find the other dealer I found before :-(

Anyone thoughts on aged throttle bodies
Just a little bump on the efficacy of old throttle bodies???
The garage has now found that there IS a problem with airflow through the throttle body (why not before? - I don't care I have a new engine!).
Anyone any experience with reclaimed throttle bodies??? Please.....

OK last bump for a while.
This throttle body looks a bit "off" looks like some sort of wear around the edge (unfortunate at 37k miles).
Others such as this one look cleaner although I cannot see the mileage on this one.
OK 8 hours slep in last two nights - off to bed!!!
Night y'all.
