You can tune up your Nissan by replacing the spark plugs and spark plug wires. You should also replace the air filter and the oil.
There is no benefit
not necessarily unless after replacing plugs your engine misfires.
A Honda CRV tune-up should include replacing the spark plugs and spark plug wires. The tune-up should also include changing the oil and the oil filter.
Pull the spark plug wires off the spark plugs. Remove the spark plugs with a spark plug socket. Install the new spark plugs and put the spark plug wires back on. I recomend replacing the spark plug wires as well. If replacing them, just remember that the new wires are hooked up the same ways that the old ones came off.
The spark plug gap for a 1999 Honda Civic LX is 0.044. You can use a plug gap tester to check the proper gap. You should always check the gap on all spark plugs prior to replacing the spark plugs.
.03 some may change due to shipping but most are pretty accurate if the plugs are expensive...
try your ignition control sensor located in your distributor
Not to tight just snug
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.
