I would start by replacing the spark plugs. Could also possibly have a bad spark plug wire and/ or a bad coil. Another possibility is a bad fuel injector, but most likely cause is plugs.

Check the spark plug wire and change if necessary. Also, if the spark plug wire doesn't fix it, change the coil pack for the number seven cylinder. If that doesn't fix it, check connections to the module underneath the coil pack and also change that if necessary.

54 Cadillac 341 motor with a pertronix ignition. intermittent spark on #7 cylinder. changed distributor twice, wires twice rotor once. any ideas on why the misfire on #7 ???


You didn't say if you had tried a different spark plug. If you sure it's not the plug, then maybe something wrong mechanically in that cylinder- like a sticking valve that stays open and won't build compression. That will cause a misfire. Do a compression test and see if that cylinder is equal to the others.

2001 CADILLAC SEVILLE VIBRATES AT 55MPH & FASTER.


Probably not without driving it.
A vibration is usually caused by something that turns, such as the tires-wheels or axles.
But it could also be a cylinder miss or something in the engine.

I have a cylinder 6 misfire on my 00 cadillac deville. do u think the plugs need to ne replaced?


Usually, if you only have 1 cylinder misfiring, you have either a bad spark plug or bad spark plug wire. If you replace the cylinder 6 spark plug and still have a misfire condition, replace your spark plug wires. If replacing the plug and wires doesn't fix the problem, replace the ignition coil.
