If a spark plug's gap is too big, it can lead to misfires, poor engine performance, and decreased fuel efficiency. The larger gap makes it harder for the ignition coil to generate a strong enough spark to ignite the air-fuel mixture, especially under load. This can result in rough idling, increased emissions, and difficulty starting the engine. Over time, it may also cause increased wear on the ignition system components.
( 8 ) spark plugs for your 360 cubic inch V8 engine
They are in the head and some have a removeable cover. GoodluckJoe basically, if you lift the hood and look directly at the engine (the big silver thing), on the top left side of it as you are looking at it from the front is where you place the oil in (oil cap). Just above that are the four spark plugs. They are underneath the plug and coils. you would have to unscrew the two bolts holding the coils down to get to two of the spark plugs, and the other two spark plugs, you just pull the wires off. (Just pull)
You have a misfire on cylinder number 2. Start with replacing the spark plugs. That's a big job on those vehicles, so the spark plugs that are in there are probably the original ones.
Yes, all spark plugs need to be gapped... but make sure you keep in mind that if the gap is not correct - if there is not enough gap, the spark will not be big enough, and if it is too wide, then there will be too much spark. Standard seems to be .45 but I would check with a dealership near you for a size recommended by them, the underhood specifications, or the brand's specs for that application, as they vary from 44-54!
depending on the engine size they will be located in the sides of the heads. look for a rotor cap and 6 or 8 big wires, depending on the engine, then foller them rihgt down to the spark plugs.
any size that works usually a 3/8th ratchet You probably meant what size socket Its either 5/8th if the plugs are small or 13/16th if they are big
Same way as every other car. Pull the ignition wires off of the plugs, one at a time, then use a spark plug wrench and a socket to loosen and remove the spark plugs (Twist them to the left like a screw) Put anti-seize on the new spark plug's threads, then hand-tighten it into the hole the old one came out of, then tighten with the spark plug wrench another 1/8-1/4 turn. Put the ignition wire back on, and move on until all the plugs are changed. I would recommend changing your ignition wires at the same time as the plugs. Also, if you can't reach the actual plugs with the wrench, you may have to pull the engine, which is possible if you have the LT1 and big hands.
One big one that goes across all 6 spark plugs.
Did you gap the spark plugs before u inserted them into the block casue that can have a big effect.
make sure you put the right plug wires to the plugs and you did not mix them up drive safe
If you have the big ol' straight 6, in like a 1990's vintage, you'll probably want to take it to a mechanic, cuz you've got to take off all kinds of intake parts to get TO the spark plugs. (Mine is 1995.)
I have a 1998 Z24 and the plugs are under the big aluminum cover on the top of the engine (4 bolts). There are no spark plug wires...just a boot system mounted to the under side of the cover and the ignition stuff is there too. Plugs will strip quite easily if you are not careful (13 ft/lbs). Bosch 4 prong plugs are well worth the money.
