Runs better but there's a slight stumble or hesitation in one or two cylinders. It's better than it was the other day, but I had to regap a few of the plugs today since they were off by a small amount. It's probably the two I didn't fix (there's one directly under the alternator and it's a bitch to unscrew).
Still stalls in Drive at the light. I'm going to raise the idle a bit and see what happens. I also need to replace the thermostat... my temp gauge on the dashboard still isn't working. The coolant looks nice and clean, though.
