I just put my car thru the official BC tune-up. Went thru everything with a fine tooth comb. If my mileage improves, I'll report the results.

FYI, I was running the AC Double Platinum plugs. Now, of course the V Powers. New AC - 02 sensor, cleaned MAF, TB, EGR, PVC. New UIM. Changed all fluids. Tire pressure etc.

Didn't change the Temp sensor.

Also, I have never taken this car an an extended highway trip. Not even once. So have no idea what the true hwy mileage is. Always took my other car.

my neighbor does all my work so i told him i wanted to change the o2 and he said i should do both because it will help my mpg i was a lil confused but seeing all he dose is work on cars i assumed he knew more then me, but i only paid 18 bucks for the temp sensor so oh well i guess lol
