Cleaned up the garage yesterday, and organized ALL my Supra parts on the shelves. Found things I didn't know or remember I had, and now I have a bunch more room to get going on the car.
Too right there, Ray. With the car up on ramps, I could get to the bolts from underneath, and the confined space is where ratchet spanners really shine. Biggest problem I ran into was that the top bolt simply would not crack; the bottom one gave fairly easily, but at one point, I was lifting the car's suspension up and had visions of lifting the whole front of the car off the ramps - anyone bench-pressed a Supra before?A couple of decades ago when this first happened to me, I took a short piece of copper tubing, had my way with it with my doesn't take no for an answer hammer and a file and that lasted about 15 more years. By the time that finally failed, I just ordered a new set of contacts and a plunger. Maybe brushes too. I can't remember. But all of it cost less than a $20 bill. It's an easy fix except for getting the starter in and out. Last time I did it, I removed the bottom bolt from below and the top bolt by using an offset box wrench on the nut and a ratchet with a couple of extensions from above in behind the starter. That was a tight fit. But way easier than any other way I ever tried.
The AC blows cold, but it's not great. Yesterday with ambient temperature at 72 Degrees Fahrenheit, the center vent temperature was 45 Degrees Fahrenheit. Okay, but not exceptional. I didn't think to check the high side and low side pressures when the shop refilled the system. I think that I may try adjusting the EPR as mentioned by Supy1984 inDale, hows the AC in the 83 now? Curious what all needs to be changed to be fully r134 compatable. I have a mint low miles oem setup I'm going to put back into one of my cars one of these years, but still not as low miles as your car.
