First off let me say that this site and its residents are top notch in my book, the information that I have recieved on my Bonnie is priceless, ty. Now to my problem, I have a 1992 Pontiac Bonneville SSE? SSEI?, really don't know, that has a bad SC, knocking, slop, the whole bit. All the great info I recieved on this site made me dig right in and pull it off and replace a few things, well I started and got as far as unbolting/disconnecting everything, except 1, the Throttle Body!!! The SC is unbolted and I can lift it but I cant figure out how to seperated the Throttle Body w/o completely disassembling the entire Throttle Body, ie: cables and what not. mechanically im a 4 outta 10, PLEASE HELP!!

Unhook the 4 electrical connectors (IAC, BCS, MAF, TPS). Disconnect the throttle and cruise control cables from the throttle body.

Remove the support (black) bracket by loosening the fasteners on the rear head (shared with the crossover heat shield) and TB. Then lift the entire thing out in one piece, remove the TB after it'* out of the car.

Well I am a 5 out of 10 and managed to take mine apart last summer (the Throttle Body) -- oh yeah and put it back together again!


The throttle body is not that terrible on the S1 SC. It is a PITA on the L27 (non-supercharged) becuase there is a nasty bolt to get to.

There should be like 3 bolts on the TB itself and you have to take off the bolt for the Cruise control bar thing that also holds the TB on.

Just be careful when you disconnect all the sensors, the plastic clips like to break off on the older cars.

oh btw welcome to BC

The Throttle and Cruise cables, do i pinch them on all 4 sides to get them outta there. and I have my fuel rail with the injectors up and out, do I need to cover the injectors or anything, seems to me like the shouldn't be exposed, maybe? lol sorry if that one was funny.

Set your fuel rail upside down so you don't damage the injector tips.

Use a small screwdriver to remove the cable retainer clips from the pins, then squeeze two sides of each cable sheath as it passes through the bracket to release them. Needlenose pliers work great for this.

you guys rock, My SC is off the car and on my bench. I removed all the nosecone bolts and WOW!!!!!!!!! does she smell pretty! What'* the tool called that I need to remove the nut over the pulley? and how do I drain that sweet smelling oil before I remove the nosecone?

For removing the oil, I find this method to be fairly good.

Take an old sprayer bottle, windex or whatever and put the tube of the sprayer into the SC oil fill hole... then pump the oil out via the sprayer into the old bottle. Put sprayer back on bottle when down and dispose of.

Do you mean the nut on the ned of the pulley?

yes the nut at the end of the pulley, it spins the shaft inside the SC, and where is the oil fill hole?
