I've got a 2000 Civic. At high RPMs (just prior to shifting or highway
speeds) it misfires...sometimes a little and sometimes alot. OBD codes
show misfires in each cylinder. (Not alot of helpful info!) I
replaced plugs, wires, cap, rotor, and PCV valve. It still misses and
the OBD light is back on. I'm thinking that maybe the ignition module
is faulty.

Any other ideas out there?? THanks!!!

What are all the actual CODES? I'm guessing you might also have a
"catalyst below efficiency threshold' code too.

What's the mileage and when did you last run a bottle of injector
cleaner (or gasohol) through it?

Oops!! Too late! Used my OBD2 scanner and cleared them. But it was
misfire codes, not catalytic converter codes.

Not a bad idea on the injector cleaner. But I'm still thinking its
ignition, not fuel.

The Civic has 70K miles.

Buddy, you don't know ZIP. And neither does anybody else at this point.

Clearing the codes was not a bright idea. Wait 'til they come back,
read and record them, then report back here.

Are the new parts OEM or aftermarket?
