dismounting old, remounting bored TB

[VanTheMan]

maybe I overlooked it, yet I can't find a thread on that subject. I wonder if there are any difficulties to be expected with the replacing of the TB. Take the air intake out, then unbolting TB; is it a fairly straightforward job? I understand I'll have to swap a sensor of the old into the new TB: location of the sensor? For me the computer, sensor etc stuff is new, the work I ever did on my own car(s), that was in another era
Any advice if I might encounter a specific problem is welcome; or a link to a thread i might have overlooked

Well, since I attempted my 70mm swap out the other day, I have this pretty fresh in my head.

Disconnect the battery (FSM always starts out this way.)
Remove the wipers
Remove the cowl (8) IIRC torx bolts
Remove the strut brace (9) 15mm bolts
Remove the air intake
Remove the two throttle cables
Remove (4) torx bolts (T30) IIRC
Loosen (2) nuts on a support bracket below the Throttle body (on top of the tranny) 13mm

Once the bracket is loosend, the TB has to be pulled away from the plenum (1/2") to clear an alignment pin then it can be lifted out.

X2 - dont forget a new gasket the sensors are on the TB, cant mess that up. just need more torx bits for that.

May want to clean any o-rings on the sensors and lube with dielectric grease.
You may very well be able to get away from replacing the gasket?? Just be careful in removing all of the bolts and clearing the alignment pin so that you won't damage it.

My tips:

-Remove the cowl, it really does give you a lot more room to work

-Be careful to pay attention when removing and reinstalling the throttle and cruise cables

Also check the bored TB before installing. Make sure it is not sticking at all and then hold it up in front on a strong light, if you see any gaps letting light through on the edge of the butterfly your car will not idle right when it is installed

im just taking it off to clean it. whats the deal with the throttle & cruise cables? are they hard to unhook and re-hook? thats the part that scares me (not being able to re-hook them properly).

also, should i take the sensors off the TB when i have it off the manifold? Grayslater said to clean o-rings so i assume that means taking off the sensors. does the TB have an Intake Control Valve like Jeep TB's??? JW

I thought from your thread title that you wer epulling your OEM TB and replacing it with a bored one

The cables aren't too difficult, they are just a standard barrel end and as long as you keep them in the cable holder (which you have no reason not to) you just need to be careful not to twist them

Once you remove the holder bolts you will have some room to work with the cables themself

As for sensors they can only go back in the exact way they came out, the IAC is very easy to remove once the TB is off

Just take your time and you will be fine
