Got p1457. Snapped 1 screw head off so I decided to get another cannister at boneyard. $7 took off old cannister and was comparing them under car. Than I put the old one back on by mistake. Duh. Have to jack up car again. I found a nice pair of Acura 16" alloys with new tires at boneyard. Of course my accord is 15". I hate passing up nice finds at yard. My rear tires are 40% tread maybe? I can give them my rims as cores so tires/wheels are only $20. Oh well.
