. '82 Chevy S10 rough idle after Spark Plug replacement Group: alt.trucks.chevy Date: Fri, Sep 19, 2003, 8:25pm (CDT+5) From: snipped-for-privacy@earthlink.net (Matthew=A0D.=A0Clark) I just replaced the spark plugs in my recently acquired Chevy S10, and was upset to find that after putting in the brand new shiny plugs, the truck actually idles rougher than before. I'm pretty new to auto mechanics, but this is my project truck and I'm using it to learn more about it all.
How should I proceed? (ahhh.........a question.........and a good one)
It seems like one of the cylinders isn't firing, but I don't know for sure, so I guess I'm going to take the new plugs out one by one and check them for any damage or goop.
Is there something simple I'm missing? (ahhhh..... question #2 ....)
Thanks, MattClark =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Matt, Wtih the truck running at idle, disconnect one ignition wire at a time at the spark plugs. The one that DOES NOT seem to make a drastic difference in the way the truck runs will lead you to the area quick.
When you find the affected cylinder.....
1) Check the ignition wire connector good, ensure you didn't fubar the terminal end or the wire.
2) Pull the spark plug, check the gap and the electrode.
The above should narrow it down quicker than yanking all the plugs. If all you did was change the spark plugs......one of the above will hopefully cure your symptoms. The unfortunate thing is......you may have gotten some trash down in the cylinder wihile the plug was being changed, but this will usually cause a "knock" if it's enough to cause problem.
Now this is all "ass u me"ing that all you did was change the plugs. =
that is all you did.........................right? _ _
