yes it does, every car has spark plugs or it wouldn't start.
your engine will start but run badly on a multi cyl. ie. more than one only 1 plug may be down, not often more than 1 together
My 93 camry has no power from the distributor to the spark plugs. The car unable to start.
You should replace the spark plugs when your car won't start first time but does eventually.
Check/replace Rotor Check for spark at plugs
You will still have spark, car will try to start or backfire. If no spark at all the plugs see if you have GOOD spark from coil. If coil is working then you will find the problem in between the coil and the plugs, probably a distributor component issue. The ballast resister is a possible cause also.
Yes, when idling and driving.
if the battery isn't dead, or the terminals loose or dirty, number one cause - ignition problem (spark plugs not getting electricity)
No spark? Leaking injectors?
Usually the spark plugs or the timing.
No,car will not run rich.Infact it gives misfires since escaping fuel will be the ultimate result if we use wrong spark plugs.
