best way to remove on a 93 sse supercharged?


i'm running out of bandaids

Just 2 screws on the throttlebody. Just remember when replacing it you want to set it to .4 - .5 volts at closed throttle and around 5 at wot. Some are not adjustable, but you still want to verify it is right.

its not the turning of the screws I'm concerned about, Its the getting to the screws thats my problem


as for adjustment 93 and later is non-adjustable

Remove the throttle body.

Removing the thermo housing is much simpler.

anyone have pics? I checked the tech info but i'm lacking in the step where you wave a magic wand and the sensor comes off

Remove the Thermostat Housing... It will make it a lot easier to remove the TPS.. While you are there if you haven't already replace the thermostat and gasket with a 180...

Sqela... How soon do you have to replace the thermostat?

how soon?

Sorry... I meant... How soon do you need to replace the TPS? Has it failed?

from driving and according to my scan tool yes it is dead as a door knob. i already got a replacement, just need to install it. would i be better off get a junkyard long block and swapping it in

Nick I was going to send you a couple of items if you could wait to replace the TPS.. But if its dead as a Smart Brick then you need to replace it ASAP

removed airbox,tb, and powersteering and got it out

But you can make it adjustable, I know there was a thread on it somewhere, maybe *mmhmmmm, looks around...* IN THE OTHER FORUM THAT I WONT MENTION THE NAME OF BECAUSE BIG BROTHER IS WATCHING....

I didn't see this post soon enough but you didn't have to remove the TB.
Just use a pair of vise grips to loosen the two screw and then turn them out by hand. It worked for me.

I, too, have asked for tips on the best way to get to those screws...if only GM had rotated the throttle body design to make access easier...
I've removed the egr valve on mine - it was easy to remove and it helped alleviate the bloody knuckles. Lesson learned - don't even think about trying to replace the TPS while the engine is hot (ouch!).
It's also too bad GM didn't use self-retaining screws for the TPS and the IAC, but that's another topic.

The '93 TPS isn't adjustable like the '92 and older were, and you should be glad yours is a '93. Just install and drive...
