spark plug gap?
hi,
i replaced my spark plugs a few days ago (well my dad did, i just watched :D), anyway, he set the gap on the first one, but we forgot to on the other 3:( (we got distracted with something else), but the car is running fine im just wondering, what effects would a larger spark plug gap have? oh, does anyone know what the gap is in mm? |
i forgot my gap for my plugs, but i could have sworn it was at .042 inches... or 1.0 mm's...err, i think i'm smoking something, someone correct me. basically, too large of a gap could cause misfire, engine knocking, or i would imagine that if all the plugs are mis-gapped, it wouldn't run at all. thats my ASSUMPTION, but if anyone knows a better answer than i've given, please correct me.
peace |
0.040 I think.
To large a gap will put extra strain on the ignition system. I'm not really sure how severe this is, but it would probably be a good idea to take the 3 plus out and gap them properly. It will take all of 5 minutes. |
thanks guys,
i'll do it tomorrow, and i found the protege mechanic book, it says 0.043ins so you guys were right, 3 one thousandths wont make a diff |
I happen to have my Mazda 323/323 Protege Owner's Manual in front of me. If you turn to page 9-3, there's is a section on the bottom right that shows a chart called "Electrical System." In it, it descibes the Spark-plug gap at 0.043 (+0.000/ -0.004) in, and 1.1 (+0.0/ -0.1) mm. So I hope that helps in clearly up any confusions on how much you need to properly gap your spark plugs.
