You distributor cap and rotor should also be replaced. If still no spark. check the compression on the low cylinders to see if you have good compression.
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.
the problum is your on board computer. it controls the firing of you spsrkplugs. have seen this problum quite often.
If you are aware of which two cylinders are NOT firing, I would change out the spark plug wires and the spark plugs with brand new for those two cylinders. If you aren't sure which cylinders AREN'T firing, then do a complete change of new wires and spark plugs. HINT: Try not to use Bosch plugs... I did, and had all kinds of trouble with them even tho they were inexpensive and supposed to be just as good.
4-cylinders have four spark plugs, 6-cylinders have six spark plugs, 8-cylinders have eight spark plugs, etc, etc, etc
try changing your spark plugs if theres any.
simple,design,it doesn't effect cylinders that are not on compression ,it allows single spark controll
The main reason a car misfires is because the spark plug wires are not installed correctly. Check the car's firing order to ensure the spark plug wires running from the distributor cap to the spark plugs (in the cylinders) are in the right order. One or more spark plugs could be damaged or worn so the firing order is correct, but the spark plugs are not sparking into the spark plug wires to ignite the engine.
it depends on the number of cylinders.. if 2 cylinders it has 2 spark plugs if 4 then it has 4.
It depend on the Cylinders...For example, If a car has;4 cylinders it has 4 spark plugs6 cylinders it has 6 spark plugs8 cylinders it has 8 spark plugsSometimes there are 2 plugs per cylinder. Such as the Ford 2.3L 4 cyl has 8 plugs and the new gen Hemi's from Dodge have 16 plugs on a V8 engine.
There is no firing order on a diesel engine as it has no spark plugs to fire. The valve timing controls the sequence at which the cylinders ignite the fuel.
Could be,Firing order is messed up.Ignition module is bad.Bad spark plug wires.Bad spark plugs.
No the spark plug wires have to be in firing order
