Thanks everyone. After 170 more miles of driving on the freeways and around town, the CEL went away on its own.

By the way, with the non-oxygenated 88 octane for $3.99/gal, I'm getting about 10% better gas mileage than the Costco 91 with up to 10% ethanol for $3.79/gal. So in my case it's worth it to pay ~5% more to get ethanol free gas. With the higher elevation in Utah, I assume 88 octane should be fine.

 

So if someone _does_ need to change the sensors, any advice on getting them unplugged with such little room to reach into them? That was how this thread started... the original noted he could potentially get them unscrewed but how to unplug the connectors when you can at best reach one hand to them?

 

 

Thanks! I was hoping someone knew a trick to avoid having to undo the drive shaft... but good to know.. just do it and get it done.
