You should have your valve cover checked. The same thing happened to me two weeks ago, and they replaced my valve covers and spark plug wires and i haven't had any other problems
If your plug electrode is coated in oil, the actual cause of this is likely a failed valve stem seal. When this seal goes bad, oil can leak along the shaft of the valve, and into the cylinder, where it then can coat the spark plug, and generally make that particular cylinder run like crap. Incidentally, if one has gone bad, it's generally a good idea to change all the seals.
Also, if oil is on the electrode side you may have a blown head gasket. If the car has been driven while overheated or is regularly driven at high RPM (as in racing) then a blown head gasket is a likely culprit. In either case a compression test should be done. Each cylinder should reach about 155 psi.
Possible wrong heat range of plug. Make sure you have the right plugs for the vehicle.
they could be bad spark plugs as in not a very good brand. or maybe you didn't put the wires back on the right spark plug.
try changing the spark plugs
NGK platinum plugs
Obviously- the spark plugs were not the issue :)
Only if there's something wrong with your old spark plugs.
Changing your spark plugs could theoretically make your car faster but not enough to make a noticeable difference. Changing your spark plugs when they are worn will increase your fuel mileage slightly.
Changing spark plugs can be an easy task. Disconnect the battery and the spark plug cables, remove the old spark plugs, replace with the new spark plugs, connect the spark plug cables and the battery.
Changing spark plugs is an important task. To do this, disconnect the battery and spark plug cables, and remove the old spark plugs. Next put in the new spark plugs, and reconnect the spark plug cables and then the battery.
It could be caused by not getting the spark plug boot on quite right after replacing the plug wires.
When changing the spark plugs of a car, it is important to remember to gap the spark plugs. The gap for this cars spark plugs are 0.051 inches.
No spark from coil, bad plug wires, or bad plugs.
Changing spark plugs is relatively easy. Disconnect the batter and spark plug cables, and remove the old spark plugs. Next replace the spark plugs with new ones, reconnect the spark plug cables and battery.
Changing spark plugs is an easy task. Disconnect the battery, disconnect the cables, remove the old spark plugs, put in the new spark plugs, reconnect the cables, and reconnect the battery.
Changing spark plugs is pretty simple. Disconnect the battery, remove the wires to the spark plugs from their location, remove the old spark plugs, put in the new spark plugs, plug the cables to the right spark plug and reconnect the battery.
No you do not need to replace any plugs at all when replacing wires.
yes it can
No. Spark plugs have nothing to do with your turn signals. Try changing the turn signal bulbs. Spark plugs are only used for the combustion of the engine.
how would you go about changing the spark plugs in a 1999 Lexus ES 300?
Spark plug tube seals need changing
When changing spark plugs it is important to know their location under the hood of the car. For a Toyota Rav4 the spark plugs are under the engine cover that has the car symbol on it.
Could be several causes: Clogged fuel filter. Clogged/dirty fuel injectors. Spark plugs need changing.
