check out my plugs
Just pulled my plugs today, and they all look, more or less, like this one. I looked at plug reading charts on the internet to figure them out but wanted to check with experienced folks here, too. They look whiter than normal, right? or do they just need to be replaced without worry? does this one look to be done with its service life? I'm not quite sure when they have been changed last as my dad took care of that sort of thing when it was his car.
I also just found that there is a 1222 lambda control error with the stomp test recently. I couldn't find any obvious vacuum leak sources and have an O2 sensor on order. Would a faulty O2 sensor produce the (lean? rich?) condition that would manifest in a white spark plug? Any and all insight appreciated. TIA
P.S. any tricks/helpful tools to getting the O2 sensor out would be helpful, too. I tried to see if it would budge today and it didn't . I feel like it's going to be a bear to get it out. Currently have it soaking in PB blaster. I've got an O2 socket and a breaker bar, but it's still tough to get any sort of leverage.
