I only wonder about the o2 sensor due to past experience with non oem parts (ie, walker). I know most older toyotas have issues with the bosch parts and only work with denso for the most part, but the opposite seems to be the case with subarus (makes sense with bosch being the oem I suppose). maf has been checked, knock sensor is next, probably take a look at that tomorrow during the oil change.

Checked the knock sensor, cracked. Replaced with an OEM sensor (updated part number). Tomorrow I'm headed up to coeur dalene so we'll see if there is any improvement in the mileage.

I suggest you reset the ecu before you take that trip. Use the green and black connectors by the ecu. The way how is on here.

Didn't have a chance to reset the ecu yet, but I did manage to get 23.5 mpg this weekend, a full 3.5 mpg increase.

How do you hate Bosch products?

I can safely say that's the first time I've ever heard that.

Anyways, carry on, good luck, I don't have anything to add that hasn't been mentioned
