S10 spark plugs keep breaking and make it misfire??

A month ago I replace my delco sparkplugs because one of them was cracked from the side wall and looked like it exploded and causing my 2.2 s10 to missfire. It is starting to act the same way. When im driving slow in a high gear and then i step on it, it hesitates to gain speed and it backfires. It just started doing this again after I replaced sparkplugs for same reason. What could be causing this??

    I had the sparkplugs profesionally installed. I currently have the service engine light P0440 because the the fuel pump is not completely sealed, when gas tank is full, it smells like fumes all because I had recently changed the pump because I thought it was bad, the problem was that the Jet Performance module had become loose, therefore making pump turn off. Could this be the reason my sparkplugs go bad?

Hi

Most unusual !

Possibly damage occurring on the installation of the spark plug, putting slight crack in the porcelain ?

Check if it´s the same plug that´s gone again.

If so renew it again carefully, from another spares supplier.

Good Luck !

Don´t forget to give me a FixYa rating , Please !

    Hi



    No, I have never known this problem to happen, other than through incorrect instalation of the spark plugs, ie:- apprentice whacking them in, with an air ratchet, dropping plug on the floor, or faulty manufacture.



    You must get your fuel leak rectified as soon as possible, otherwise you could be in serious trouble with a fire.

The porcelain spark plugs keep on cracking when the car is being used


Is the porcelain "cracking" or are they getting "carbon-tracked"? (see example photo of carbon-tracked plug below).
It is common for carbon-tracking to occur if your original plugs were carbon-tracked and you replace the plugs without replacing the wires. If the plug is carbon-tracked, the boots on the wires or the coil boots (coil-on-plug ignition) are also carbon-tracked. If you do not replace the wires or the coil boots, the ignition will still misfire by following the carbon-track on the inside of the boot. This will cause your new plugs to also be carbon-tracked within a short period of time (days or weeks).

There is no reason I can think of for the porcelain itself to actually crack other than faulty installation techniques or possibly, cold liquids getting poured on extremely hot plugs.

Cylinder 3 misfire


Check ignition lead - ignition cap and sparkplug. look signs of wear or cuts on the lead. The cap should be tight on the sparkplug. The sparkplug must be free of cracks and not unusually blacked out. Replace if in doubt.

Quick test is to open the hood in the dark. Let someone start the car and look for blue sparks around the lead and sparkplug cap. Be careful - keep away from moving parts.

Car won't start, new battery, starter ok, just won't kick over Saturn 2004, 80,000 miles, oil change 2 months ago,


If the starter/Battery are ok.Check for spark by pulling off a sparkplug wire,have someone try to start hold wire near sparkplug tip you'll hear the spark jump to the plug tick..tick..tick..sound.Be carefull to hold wire just far enough to hear spark,also this is the secondary circuit from the coil it's high voltage wear a glove.If you smell gas youre geting gas if no spark it is 1 of the following.Bad Coil, or ignition modulator, crack in distributer, cracked wires that cause spark to not reach plugs.Good Luck.
