I don't think we really get tired from wrenching but we all need a break, I didn't touch my car for over a month when I had the ECU problem only to find out if I had tinkered a little more with it, I would of found that the issue was the high fuel pressure!
I know the feeling well, my buddy too and his RB25 240SX. All he has left is intercooler piping and that's it, he can start the car. He has been slacking on it for a month now.
I happens, I guess that's why you see so many, "I couldn't resist," kind of introduction threads for people who got out the game a few years ago and saw another Supra.
With all of this said, Steve, I have your address.....get to work on your car.
