I started today's project in the garage rebuilding my Impact wrench. It would just start spinning when hooked to the air hose. Deep in the bowels of the handle is the seal that got hard, and looked like a mouse had chewed on it. I could not find any instructions from YouTube for my model. Just a 13 second video of some guy with the same problem I had. So I pretended I was back in the olden days before the internet, and figured it myself. Not really that hard once I got the rubber outer grip off, and figured out how to push in the two clips, and pull the part above from the handle.
Then I tackled my throttle position sensor on my 86 El Camino. I can't just order parts for it by car type, because back when I took the original carburetor off, the throttle body setup is mostly built of parts from a fuel injected pickup in a junkyard. Again no real instructions, but it is just a G body FI setup and similar to others. I figured it out once again with no real instructions.
The good news is a Made in USA TPS is just $32 delivered to my door.
I converted the Elky to fuel injection over 12 years ago, and +100K miles ago. I would have to get out my records to find the exact mileage and date. It was the best thing I ever did to that car. Since then, it starts and runs like a modern car and no more hesitation. Now days there are dozens of turnkey kits to do that conversion. Not back then, I was ahead of my time I guess. It still runs great, so I have no desire to fix it if it ain't broken.
