Idle very low when stop, then recovers - 7/22/2008 4:03:02 PM

Hello, I have a 2000 protege 1.6L auto with about 140 000 Km on it. Recently, I changed my spark plugs and air filter. I gapped the plugs at .041 (manual says between .040-.043) Ever since then I noticed that my idle speed gets really low, to the point of almost stalling, whenever I stop. After a few seconds the engine recovers and idles consistently at 300 rpm. Since I didn''t have this problem before I changed the spark plugs, I''m thinking the gap might not be correct. Does this sound right? Is spark plug gapping really that sensitive?

Any insight would be much appreciated!

Thanks!

The gap is not usualy THAT much sensitive. I would take a look at the EGR valve, there is a post here on how to locate, disassemble and clean it. I don''t know if it''s the same as on the 2002''s, but my EGR needs a good cleaning every 50000km.
