The rubber insulator all cracked can not give enough spark and therefore misfire.

You can replace all 4 but a misfire would easily show itself with a flashing cel under acceleration.

I dont understand

what problems it causes to the car? will it blow up engine or some major damage can occur if left as it is? lets say if i`ll drive in that condition around 2000 km?

A misfire can result in unburned fuel to that cylinder, resulting in oil dilution from that cylinder down to the oil in the crankcase. This causes excessive wear to the rest of the engine.

A bad coil doesn't necessarily present as a seat-of-the-pants misfire. Sometimes it's just reduced performance and gas mileage.

Hey guys,
I decide to remove all plugs and clean with some special connector cleaner all the connectors, coil plug holes, spark plugs, wires that connect to them... maybe something like rust or dirt is there (simplest option to do i think), but i`m confused is there any connector at the bottom of the spark plug inside engine? or that part just sit`s down without conecting something at the bottom?

and if yes how do i clean that part in the engine? without dismantling engine of course

If you are talking about cleaning the part in the red square, just unscrew it and pull it out. Should be an 18mm socket.

That's the part that makes the spark that ignites the air/fuel mixture. It can be cleaned in a small variety of ways. I've used some fine emery cloth followed by a shot of brake parts cleaner to remove residue. Careful of your eyes. And wear gloves.

Be careful threading the spark plugs back in. Don't cross-thread them. Very bad.

Do it by hand, or with just the socket, and possibly an extension, on them and no handle. If they thread in that way with no resistance they can then be tightened up with the handle. If you don't have a torque wrench, tighten them until they seat, and then about another eighth of a turn. But get a torque wrench.

Did I say to get a torque wrench?

I did clear those parts and gonna leave that out of car for all night to "drain" all the liquid if some left inside just to be safe

+ the cable in the engine that plugs in that connector i did also cleared

Hand Finger Wood Household hardware Thumb

I got this cleaner special for contacts cleaning

and gonna use that as well on the spark plugs,
i did buy special spark plug removing wrench today, so i think remove and install wont be any problem, also I`m disconnecting the battery before removing anything

maybe i wrote something incorrectly,
do this part in red square touches something inside engine? is there some connector or it just "hangs in the air" down there and it not connects to anything?

No, it should definitely not touch anything. A spark jumps across the gap and ignites the air/fuel mixture.

Check the gap while you're at it. Spark plug gapping tools usually have a gauge built in. I don't have the spec handy at the moment.

That is good if no connector on other end, thank you.

ya, gaping tool

i saw in some videos as well and forget to buy that thing... i will try to check just with some normal rulers and carefully increase/decrease with some plaiers if gap is big/small

Thank you Scotty, you are very helpful

Thank you.

Buy a gauge. A ruler won't be nearly as accurate.

There are other types, but I prefer this one.
