My error code was P0135-- O2 sensor heater circuit, bank 1, sensor 1.

I notice the engine idling rough as well, so I'm pretty sure the sensor is bad (or going downhill quickly). I ordered a new Bosch sensor off Amazon for $35, which I thought wasn't unreasonable. WAY better than $70 at O'Reilly's. Funny thing about my check-engine light, though, is that I can start the car, and it won't come on immediately, until I rev the engine a little, or give some gas while starting in 1st (even if the actual rpms don't rise). It doesn't give a fault code with just the key on.

In side notes: I got 39.9mpg at my last fill up (which I thought was a short tank from the fill up before), and (based on eyeballing the gas gauge) it looks like this tank is going to be similarly close to or better than 40mpg.

I want to second Detail Man in thanking William for his great tips. Most of them I already do, some of them I can't, and others I will start implementing.

I asked if there was any way around using a cartop sign, and was told "definitely not." Oh well.

I do pretty well at knowing which routes have the least number of stops (I literally count and compare stops on all possible routes in my head as I'm driving), and I study the lights and know how the timed ones work together, and how the sensored ones work (which ones are more sensitive and which ones to avoid if at all possible).

I could do better parking strategically-- coming up to the address so that I'm parked facing downhill and can coast for a ways before I have to restart after a delivery, etc.

I've been getting better at utilizing ALL the gears for DFCO, instead of only using 2nd or 3rd right before a stop or on a huge hill. I've started trying to use 4th and 5th on longer and not-so-steep hills.

I avoid all those road enemies (stop lights/signs, speed bumps, gates, and traffic) as much as possible...often, I'll consider the level of traffic and opt for a stop sign (a sure-but-short stop) over a known light (a likely-but-long stop), even thought there's a chance I might hit it when it's green. I don't know if that's actually a more fuel-efficient strategy, but it seems faster to me.
