Hi Guys,

I was cleaning out the throttle body and ISC chamber a couple weeks ago, and during the reinstall I snapped one of the ISC bolts :(

In efforts to fix this, and the resulting minor surging issue, I am looking at getting a set of bolt extractors/E-Z-Outs to remove the bolt shaft from the throttle body, and to do this properly, I think its best to take out the TB to work on it.
I bought a 2nd hand throttle body, complete with a reasonably new ISC and TPS, for $30, but stupidly forgot the fact that my car has cruise and the donor car did not, so no deal on a TB changeover, but still, a good donor TPS and ISC.

Anyway, I removed the donor, non-cruise TB easily enough; but my cruise-equipped TB looks considerably more complicated, and the workshop manual doesn't really explain it thoroughly enough.

Has anyone taken off a cruise TB and can give a step-by-step or any pointers? Secondly, has anyone had experience with bolt extractors/E-Z-Outs on small bolts such as those on the ISC (8mm head)?

Any help would be greatly appreciated! :happy:

i have used easyouts and they are great, removal of the throttle body with cruise is not much more involved, just label vacuum lines etc. have a really good look and you find there is not a hell of alot to unplug to get it free.

To remove the TB from the vehicle, does the cruise control bracket need to be detached, or will unplugging the vac lines suffice, do you need to remove it in order to unlink the accelerator cable?
I like the idea of using easyouts but have concerns on using them on a bolt so small :/

Spot on. You need to drill a hole in the middle of the broken bit that is still in there, pretty much impossible without damaging the much softer alloy around it. An easyout that small will snap off anyway, when you apply some pressure to it. Tried them before on 2 broken exhaust studs, waste of effort really - needed to be drilled out by a workshop and resleeved with helicoil.
Your problem could be solved by drilling out and tapping thread to a slightly bigger size, possibly. Take the bits to a workshop and explain the problem.
