I have a small leak lean code and the timing chain has been clicking. I’m mid repair of the timing components, but I wanna know if these spark plugs say anything specific to anyone of experience.





They are two years old.

 

They look oldish and fairly consistent. It is fuel injected, reading plugs for tune is somewhat futile.

 

Excessive gap, electrode erosion, indicating high temp.

In other words, too lean.

2 cents, and cheers,

They could be affected by a lean condition. Some erosion of the electrode and ground is normal. But the condition of the porcelain suggests the plug is running "hot".

Find and fix the leak. Get the timing chain sorted.

Get new plugs. Be sure they are the correct plugs -- my preference is to run what the factory installs rather than depend upon some plug maker's chart which claims its plugs are the "same" as the factory plugs (which is sometimes *not* the case) -- and gapped correctly then install them torque them all down correctly and drive the car.

 

Excelent input. The car wouldn’t start wouldn’t click or anything with a P2300 code. I’ve suspected my coil pack running out for some time and for whatever reason being disconnected 4 days for the timing chain replacement (completed and success) has lead to the coil finally dying.

It got me to work, then my moms, and wouldn’t start again when I tried. The 1 and 3 studs coming out of the coil pack were dark and fouled up. The 1 and 2 plug wires (at the coil pack) had rust colored dust on the inside of their boots, while the 3 & 4 wire’s boots did not. The spark plug wires are 6 months old.

It’s been making loud and rapid clicking, clacking, clapping sound which I thought was the chain. I believe now it was misfire.

 

I agree with others... white typically means you're running lean and hot.
