Spark Plugs giving poor spark?

Bad coil, bad coil wire, insufficient voltage to the coil, insufficient trigger ground to the coil.

Low battery voltage

12 volt wires on the coil reversed

Plug wires with high resistance (old, cracked inside)

Bad "ground" connection on the plug.

Remember that the place where the plug screws in and SEATs is the ground for the plug. That ground connection (like all electrical connections) needs to be very clean.

Check the coil. It would appear that the coil is on its way out.

Could also be the electronic ignition that is becoming faulty, however, these tend to fail outright.

My bet is the coil.

possibly coil or wires, if finances are a problem like with me, fine sandpaper on all contacts could prove to be very helpfull

it is time to replacement your spark plugs.

you should change youre spark plug wires not hoses they are not hoses water does not run through them

you could need a new coil or new plug wires.

weak coil...bad plug wires

maybe its the spark plug hoses have you tried changing them.. if not then try it has to be your ditributor cap change that also.. go or call your local kragen and they will supply u with all ur information... good luck

Since its basic function is weakening, it is time for a replacement!
