ae86 not running right, injector?

[jondee86]

After the engine has been running, pull the spark plug out of number
two cylinder. If there is no spark the plug will be wet with fuel. If there
is not fuel (dry plug), the injector is bad.

If there is fuel but no spark, pull out the plug and clean it thoroughly !!
Clean the tip of the electrode and the earthstrap with a thin file (points
file will do). Remove as much carbon from the insulator as possible.
Heat the tip with an oxidising gas flame to remove any oil or grease.
Now set the plug on the bench to cool.

While you are waiting for it to cool, take a new plug, fit it to the engine,
and start the car. If it runs nice and smooth on all four, throw the old
plug in the trash
