So glad to have found this forum, seems like I will be visiting here a lot.
I just bought a '93 Civic Dx as a commuter. It has about 140,000 miles on it and is an automatic. Sometimes on take off it stalls and lags out a little, then goes away. This does not happen that often and didn't when I test drove it. It failed smog today, but only in the 25mph NO column.
15mph NO (PPM) Max 731 MEAS 715
25mph NO (PPM) Max 798 MEAS 1010
Everything else passed pretty well below the MAX range. It barely passed the 15mph NO test. From what I've read seems like maybe the cat?? I have not done anything, but am going to change spark plugs and wires just because. Any input is highly appreciated.
