I have a 93 ex, and recently it has been idling rough when it gets warmed up. its also gutless when its running rough, sometimes it will switch back to normal for a few minutes while driving and then back to running rough.

i have changed the plugs and wires and its still the same. i have no idea whats causing any feed back would be appreciated
thanks!
 






May have a failing fuel pump. Check fuel pressure under load. Often a cold pump that is failing will put out adequate pressure, but once warmed up it will quickly become unable to supply enough fuel.

Any codes?
