Oxygen Sensor questions

[Isphius]

How would carbon even get into the intake? unless you car backfires everyday. I went to meinike to get a 4 wheel alignment and they told me i needed new wheel bearings on all 4 wheels. 75$ each for labor and 60$ each for the bearings and grease seals. so i basically gave them the finger and never went back there. I went to a local shop around my house and they charged me 60$ for the 4 wheel alignment and now its fine. lol. The only reason i did this was because my rear wheel was misaligned, one of the arms was out of adjustment. I would also say just buy the oxygen sensor...i changed it myself in 10 minutes, and i have mechanical experience but never changed an o2 sensor. Just unplug and unbolt the old one, change the plug to the new one, shrink wrap the connection, and bolt it back on. my car actually seems to have a little more power and run a little smoother right through 2500~~3500.
