I drive a 94 integra 5speed. I've had my car inspected twice in the past week, and my car only fails the emissions. I had an oil change two weeks prior, and I do need a tune up. The readings the first time That failed were:
Low speed Hc 255 (standard 146)
Low speed co .96. (.82)
High speed NOx 1962 (1026)
Low speed NOx 3090 (1134)
Since my car is twenty years old, I figured my car just needed some cleaning so I bought the "guarantee to pass" stuff at auto zone. Driving a full tank to a fourth tank took me eight hours of hard driving, and I still didn't pass the second time.
Low speed NOx 1935 (standard 1026)
High speed NOx 2041 (1134)
I am barely not passing, and the stuff cleared up everything else. I might need to replace the catalytic converter. My question is, would buying another guarantee to pass do the trick, or should I just go strate for replacing the cat? I also havent tried the sea foam method. I've owned this car for a few months, and I have no idea how old the cat is. My guess is pretty old since 90% of the car was stock when I got it. I'm leaning towards replacing the cat but that can get expensive.
