You did not specify year so I will assume it is an older one.
If it is spark related then a cracked distributor cap ( so small you may not see it ) or rotor, and dont forget the plug wires, one or more may be bad or grounding against the engine before the plug.
I suggest replacing them all ( cap, rotor, and wires ) then check timing.
the engine is constantly vibrating and it dislodges the spark plugs
There would be six spark plugs for a six cylinder engine. One for each cylinder. Unless it is a diesel, then there are no spark plugs.
That would depend on which engine you have in your 2003 Ford Excursion : The 7.3 liter diesel engine doesn't use any spark plugs The 5.4 liter V8 engine has ( 8 spark plugs ) The 6.8 liter V10 engine has ( 10 spark plugs )
Probably not. The engine needs spark, fuel and compression to run, you are missing one of those. My guess would be the engine is not getting fuel.
where would the spark plugs at on a Oldsmobile 1989 engine
that could be caused by ur spark plugs missing or something like that i would check ur spark plugs and if not that idk.
Internal engine damage.
Worn spark plugs would cause mis-firing or non firing cylinders, both are no good for the engine, replacing the plugs may stop the knock (Could also be a different problem) But you should replace spark plugs as soon as possible.
Loose spark plugs would result in a loss of compression. This would make starting difficult and if the engine ran at all it would do so badly.
No, not unless your connect the plug wires wrong or one of the new spark plugs was bad.
The 1991 Cutlass Cierra came standard with a 4 cylinder engine. This would require 4 spark plugs to tune up the engine.
Oil on the outside of the spark plugs is caused by a leaking valve cover gasket. Replace the valve cover gasket. Oil on the electrode of the spark plugs indicates the engine is worn and is burning oil. The only fix for this is an engine rebuild.
