New guy w/ HX

[Xist]

I get "P1163 Air/Fuel Ratio Sensor 1 Slow Response."

Super Clean SilverHX! Congrats on the score!

Looks almost identical to Slambo (before I started messing with it).

Definitely go for the EGR clean. I saw a significant jump in MPGs.

Most fun mod I've made so far is the B&M short throw shifter & Energy Suspension poly shifter bushings. It's snick snick snick.

I'm real happy with Michelin Defenders.

I will also heavily recommend the Michelin Defender tires. They are low rolling resistance, super silent and have great ride.

Hey silver!
Sweet ride- just snagged my second HX recently also a Vogue Silver 99 5MT.
Very capable of astounding mpg's

I'm more of a "drive it" owner, keep it tuned up with the basics and enjoy what that car can offer. I've found that real hypermiling techniques give better results than the lean burn feature everybody squawks about, but as usual YMMV.
I am a ScanGauge XGauge fan but am just investigating the Torque Pro app via BT. I seem to recall seeing iPhone compatible in my research. Give it a search and see if it works for you??? If not, the ScanGauge has been my mainstay for nearly a decade. It works well for me.

To answer one of your questions in post #9: get a set of Michelin Defenders. These are a "low rolling resistane" or LRR tire (search sizes and brands of LRR tires on tirerack.com). Another great virtue of the Defenders is they have a long tread wear rating, making their slightly higher initial price a good value in a long lasting tire. And I found mine with a rebate, on tirerack.com.

Stock tire size was 185/65-14, but you can get about the same diameter and slighly better aero and rolling resistance by going with a narrower tire of about the same diameter, such as 175/70-14.

I get to test a lot of tires, doing what I do, but there aren't a ton of 185/65R14 LRR all-season choices. Haven't driven the Bridgestone B381, although the Ecopia's are solid. Goodyear FuelMax feels harsh in comparison to the Defenders.
