I've had a few close calls recently.
1. Both the compressor and air handler stopped working on the ac this summer. Total cost to fix was under $20, capacitors both times. Did the fixes myself, so figure I saved enough for a pin by not getting ripped off.
2. My 4runner has 376k miles on it. Started stalling during idle about a month ago. Put in new plugs and cleaned a bunch of stuff, nothing helped. Put in fresh gas, hasn't stalled since. Actually sounds as good as ever and zipping up the hills again. So was a blessing in disguise. It will bring me no joy when I do finally replace it. Will no doubt be thinking that could be an Oktoberfest, Munsters and Willy Wonka instead.
