the engine is constantly vibrating and it dislodges the spark plugs
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.
To remove the stuck spark plugs, you can break them loose and then start to get them tighter as you rotate them out. The ratchet wrench can also be used to remove the stuck spark plugs.
Spark plugs do not loose power, rather, they become worn and erroded. On occasion they may also become fouled, indicating a mechanical or fuel problem.
When replacing spark plugs on a Nissan Maxima 1995 remove the spark plug covers by twisting until they come loose. Use a socket and wrench to turn the spark plug to the left until it is released from the vehicle. Repeat for all spark plugs. Screw the new spark plugs into the vehicle and replace the spark plug covers.
possibily its the wrong plugs could be hitting the pistons
I would recommend the OEM spark plugs, AC/Delco. Excellent plugs.
If your Honda CRV cranks but won't turn over because the spark plugs are not getting spark, ensure the wires are connected. A loose spark plug wire can cause this issue.
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.
They had 2 engines available, a 2.4L 4 cylinder which would have 4 spark plugs and a 3.4L V-6 with 6 spark plugs.
Depends on the type of spark plugs. Factory plugs around 70 - 100k depending on the condition of the plugs. I would replace the spark plugs out with some AC Delco iridium plugs they will last you 100k+.
No, they don't necessarily have to be replaced. However it is usually a good idea to replace the wires along with the spark plugs. As the wires age and go through heating cooling cycles they get stiff and brittle. As you flex the wires to remove them from the spark plugs the inner conductor often breaks causing a misfire. Also when you pull the spark plug boots off of the spark plugs the connector often can break loose and stay on the spark plug, thus ruining the wire.
Use the same spark plugs as you would with a distributor, but reset the gap to .020".
