I am going in on Friday. Planning ahead, if the car fails, I plan to change the O2 sensor (I think it is a Neihoff, couple of years old) and spark plugs on the weekend and get it retested. What other components are the usual suspects? The cat is fairly new at about 7,000 miles or so.
Another question: I have been getting an intermittent code (I can't remember the exact code), but it is likely for BCS. Would that have an impact on emissions? I will eventually replace it but don't want to right now.
Anybody tried those "Guaranteed to Pass" things?
