the rear 2 sparkplugs have a sheild around them and one of them has been damaged so a socket want fit on the olug. does anyone know how to get the sheilds off. can't tell if they are pressed weilded or how they are atached.

The damaged shield is a heat shield. Here are the instructions of how to remove it. Once you have the shield off, It would be a good time to straighten out the damage as much as you can...WEAR GLOVES!! Remove the wheel well splash shield.

Remove the exhaust manifold heat shield.

I HOPE THAT HELPED YOU. Rick

could old spark plug wires cause this

Wobbles?


Does this symptom happen at idle while in park?

All the spark plugs went in without antisieze but im on the last one and it wont thread in and go on.

did old 1 come out fine? i've had the issue where threads were bad/damaged on NEW plug.

Yes it came out fine and how can u tell if threads are bad, they look fine.

it's tricky and dont take bein off much to cause problem. you could try that same plug in another hole? also tr old plug in that hole it's not going into to be sure it's not damaged now too.

I got all the spark plugs on but one and when i checked them and pulled the other ones off they smelt like fuel. My last plug wont go on wont thread have checked them for debri and it isnt damaged or cracked or broke.

IT may be stripped

TRY A DIFFERENT PLUG----EVEN PULL ONE OF THE OTHERS, AND TRY

EVEN NEW STUFF CAN BE MANUFACTURED WRONG

FRIDAY, 10 MINUTES BEFORE THE MACHINE OPERATOR CLOCKED OUT FOR HIS WILD WEEKEND!

I'M HOPING THIS IS THE CASE, AND YOU ARE NOT STRIPPED OUT!
