Spark plug condition
Hello everyone,
My car was running weirdly.
Do you think those spark plugs shows any signs that something bad is happening?

How many miles on those plugs? I would put a new set in, go make some good hard runs, then IMMEDIATELY (e.g., no cruising around) stop, let the engine cool down and check them again. Those appear to have some fouling on them. Stock heat range plugs?

Will do as explained and verify their state, thanks.

What’s the ‘weirdness’ you have? Can you elaborate?
Personally I don’t see too much wrong with them. From their appearance I’d guess you’re still using the OMP. There’s always a bit of carbon build up and yours don’t look unusual. And the center electrode looks as I’d expect from just 400 miles.
It’s actually at start-up and idle when I start to get clues that my plugs are ready to be changed. Just a bit longer cranking, and just a hint of lumpy idle.

I tested compression some time ago and it looked fine.
Car was tanked recently.
Do you mean this by sensor check?
