Wife had been saying the Element with the K24 was not herself a little sluggish when cold on cool/cold mornings. Hot or warm mornings she was her peppy self. Pulled the number one plug 2 weeks ago and seemed fine, gap was correct nothing out of ordinary. I drove it couple times and fine to me but it is her DD. Only thing I had noticed recently with it was the exhaust was starting to smell a bit more. So I ordered a set of plugs as I change them it 50k and was waiting to change them- super easy and takes 15 minutes on the E.
Old plugs are Denso Iridium IK20L's 5358s with about 40k miles on them. Both plugs and coils were changed then both Denso's. Replaced w Denso IK20TT 4702s.
Now yesterday she threw a knock sensor code but ran fine wife said. Wife did get gas at a crappy Exxon station the day before as it was on her way home from work. Crappy bc it is always running out of gas, happened 3x's she had stopped previously this year and not overly busy this time of year. Wife is not going there anymore even though it is Exxon station, we buy Top Tier majority of the time as we have 3 around us. Figuring bad gas as knock sensor is OEM also with 40k on it.
So I pulled the plugs today and cylinders 2, 3, and 4 were all out of specs and it appears the ground electrodes opened up to .055" from spec of .044", tips all look uniform. Ordered them from Rockauto as I do all my plugs. Just seems odd being a Denso 100k plug.
Anyone else have this happen?
