TRINI-2-DE-BONE

I got these plugs installed like last June. I dont think the car is running right, might have to dyno tune it again. Running too lean maybe?

Really need a good close up of the insulators to tell, but from what little I can see the color looks about right.

I say it looks good.

Light tan dry color of the tips is a sign of a healthy engine.

Dark tips with oil residue is a sign of ring wear or possibly bad valve guide seals

I looked at this earlier and thought that they looked OK...

They look like mine that came out at 85000

and thats the weird part 5 years vs 10 months... I think im going to get the car dyno tunned tomorrow cause it keeps sputtering when I left off the gas. It didnt start doing that unless i installed the used VAFC that I didnt reset before i installed it but did dyno tune it afterwards and it felt better but recently its started going back to that and I thought it was these plugs but after changing them today there isnt a change.

The plugs look exactly like they should. Sputtering when getting off the gas could be IACV or maybe the map in the VAFC is set to rich in that range? Could also be a bad O2 sensor or a chance failure of some other sensor.

You sure you got the correct plugs?

The look just fine. Color of the tips are tan and no indication of anything untowards. Hard to tell "age" of the plugs just by looking at them, especially the Platinum / Iridium ones. Once you get past a couple heat cycles, the usual discoloration develops. Both electrodes do not "pit", unlike the copper plugs.
