Ok, been a long time, but I have updates.
About a year ago while at the drive thru window of my bank, I noticed a very VERY strong scent of gasoline and thought "Wow, that minivan next to me better get that checked out and quick". Yeah... turns out it was my Buick, later in the day after getting home I walked into my garage and got punched in the face with the unmistakable smell of gas, after investigating I discovered the leak was coming from just before the rear drivers side wheel. It turned out to be my fuel filter had rusted and caused a pinhole to form, a new filter was installed and everything was once again fine.
Then about two months ago, a new problem started, the car would just die while I was cruising along at 35mph or so. No reason for it, it would just die. I asked Tom about it and he said it could be that my throttle body needed to be cleaned because carbon built up could be choking it off, so I got some TB cleaner and went to town with a toothbrush, but the problem happened again a week later. And several times after that with no apparent cause, the only consistent thing is that it always happened along this same stretch of road in almost the same spot, and the car would be fine after restarting it.
Back to Tom it goes and he's stumped, the computer isn't kicking out any trouble codes and there is no obvious cause, so he starts doing research on his end while I do the same on mine. In the middle of all this, we saw that my rear brake line had JUST started to leak after 20 years of IL winters, so that had to be replaced. Anyway, Tom's best ideas are that it could be my computer crapping out or some other electrical gremlin at work, while my research makes me think it's my crank position sensor going out.
I read several other reports from people with similar cars (W, G, C, N) bodies also with 3800's, and they were in the same boat as me. The car just dies while driving with no trouble codes, and nearly all of them found a new CPS to be the fix. I tell Tom what I've read and he says "lets give it a shot", and lo and behold it worked, the problem hasn't happened since.
Some other things I've had crop up and/or fixed was a strange electrical gremlin that caused the drivers side headlght to only work when it felt like it, a new bulb made it go away. My wipers get a bit confused on where the proper place to stop is when turned off, probably need to replace the motor but so long as they still clear the rain I can live with it. The bearings in my supercharger snout might be wearing out again, cheap ass chinese bearings, but Quiky was generous enough to send me the snout off the LeMons GTP engine we blew up back in 2011. So I can just swap it over whenever.
She's 20 years old and showing her age, but she's still my girl and I wouldn't get rid of her for anything.
