Hey guys. Maybe someone knows whats going on. I have a 2000 civic si. Bone stock. Ok fine i have a k&n air filter (not a cone) Fairly New clutch. I idle at about 900 rpm.

I took it for smog (twice) and he said it kicks him out of system for the 25mph speed test. He said rpms are at 3500 rpm or so (in 2nd gear). Said everything passed but cant even complete the test. no mechanic really wants to diagnose it. Im stuck. Any ideas out there?

Any wisdom is appreciated!

P.s ive turned some wrenches before but cant take apart the engine or anything
