93' Civic DX 1.5l

When is gets to temp it idles rough...almost sounds like it is missing. It also does this: Rev up, back down & almost die, Rev up, back down & almost die,
Rev up, back down & almost die.


I have replaced: Fuel Pump & Screen, Fuel Filter, EFI Main Relay, Spark Plugs & Wires, also cleaned the fuel injectors.

You guys have helped me out alot so far...any ideas?

Thanks!

 

First try cleaning the EACV (IACV) with carburetor cleaner. If that doesn't help, check for a possible air intake or vacuum leak.
