well the PCV valve was replaced when i got the new upper, the new upper came with a new PCV valve surprisingly enough, and we replaced the plugs as well, wires are still on there though, but wouldnt it be running crappy if they were bad? i dont think anything having to do with the fuel pump, filter, or fuel pressure because its definetely getting fuel. here is my typcial day of driving to work:
5-6 miles of hilly gravel road, speed between 25-30mph, frequent revving between idle speed and 2500 at most
2 miles of curvy backroad, speed limit is 55...i usually accelerate onto to it mildly between 3k and 3500...then i put it in OD and run about 65 on it..
15 miles of open highway, speed limit 65, i mildly accelerate again up to about 70mph, set the cruise with AC, btw AC is on the whole time on the other ones..usually the revs stay right at 2k or a little over, i might pass 3 or 4 people at most and maybe go WOT one of those times.
rinse and repeat on the way home, done 5 times a week.
how much is a new o2 sensor? and how much is the special tool to change it? or is it even necessary...can a good mechanic tell me if its working properly or not? arent there two o2 sensors?
