New tires and air filter went on at the end of April. I checked spark plug gaps yesterday. They were all within specs. The car has about 88000 miles on the odometer.

Here's a possible smoking gun. The emissions drive cycle readiness flag hasn't been set up since last year. The O2 sensor readiness flag is set, but it went off briefly at the end of January during a trip to Colorado.
