Throttle body/TPS problems
I don't usually work on my car but short on money so I decided to replace the TPS myself. I put a self diagnostics on my problematic 2000 Civic Dx after reading a whole lot and asking around about it. Now, I have a bigger problem because I kinda was harsh on those screws that don't necessarily come off easily. I banged with a hammer and a flat head little too hard I think and I broke one screw's housing on the body and I broke the other screw so it's stuck inside. Now I can't keep the new sensor in it's place. Although I started the car and ran it for two minutes, it didn't die on me. But, I was afraid to get out on the road with it. Do you think it would be safe for me and the car to drive when the sensor is not in its place? Is there any way I can do this via a tie or something? Thanks in advance.

Re: Throttle body/TPS problems
Sounds to me like you need to buy a new TPS.
For the original bolts/screws, remove TB and use a Dremel to score a line across the top of each bolt. Use a flathead screwdriver to remove.
After you install the TB with new TPS in the car, voltage calibrate it to read 0.5V at closed throttle.

I already got the new sensor. I used a zip tie for now but I don't think I can calibrate in that position until I figure out how to get the broken screw out.

Re: Throttle body/TPS problems
If on the throttle body, you might be able to cheat with JB Weld cold weld. The problem with this is dependent on how the break is and how you fix it. If you have to glue the screw in place, I would change the screw to a stud and use a nut instead so you don't have to ever attempt getting the screw/stud out. Thus will also allow you to loosen and adjust at will.
On the broken screw... Is it broken flush to the throttle body? If it is, then it's a drill out and retap it situation. I've never had good success using easy outs on totally seized bolts/screws.
If however the screw broke high enough, you should be able to grab enough of the screw with vice grips and twist it out.
