I have a 1994 civic ex and I just took it in for the 4th time yesterday to get smog checked and it failed once again. Here are the changes made so far.
Changed spark plugs, spark plug cables, distributor cap, rotor, oil change, run some injection fuel cleaner, a cat converter change to a walker 15800.
Here it's what it comes back with:
Test:
15mph 1777rpm
25mph 2047rpm

I'm going crazy over this any help would be great.
