Yeah, I got a little nervous. After I replaced the PCV valve it started my check engine light came on for the first time ever. But I had autozone read the code and it said "intake air temp" sensor, which I had moved around earlier. I pulled it out, stuck it back in and turned it upright and it worked fine and my check engine light went right off. What a relief. I was really scared there for a moment lol. I think today I might see about getting a synthetic swap for standard oil change somewhere. It's due, and I have 2000 miles of driving to do over Thanksgiving....Rear speaker replacement may also be something on the list of things for today. 12 hours in a car with blown rear speakers may become irritating...
