Dang thing needs to go back to the shop again but thought I'd ask here first. Check engine light came on Thursday and I took to mechanic right before they closed. They said it had a 173 or 178 code (I couldn't read my own note when I got home I was mad had to go again and scribbled it). Said likely an O2 sensor. They turned off light and reset it to see if comes back on. It did last night. Called about ballpark price on repair and said need to bring in a see which sensor to know. Neighbor says that should be covered under the warranty of the new engine but he's not a mechanic either. Just wondered if that's plausible. Is it part of the new engine?
Thanks in advance
