Oh, the tech also said it might be running rich, or is he full of it?
What about the gap or the electrode shape? If they open up you won't be burning very clean.<font face="Verdana, Arial" size="2">Originally posted by gLudeous:
I looked at the plugs a month or so ago, they looked fine, no carbon buildup, just grayish with hints of darkness closer to the threads.
I'm sure, though. You've got exhaust flying out the tailpipe at somewhere around 70 or 80 CFM, there's no way anything ambient could "sneak" back up to the sensor head, at least 2-4 inches into the taipipe. The exhaust, even at idle, would have enough pressure to keep anything ambient from diluting the real thing.<font face="Verdana, Arial" size="2">
I'm still not sure the burning oil wouldn't have caused a problem, they just clip the thing to the tailpipe and I'm sure burning oil fumes have HUGE HC content, so even if just a hint got to the sensor it might have popped it up. </font>
220! Well, maybe it's not so bad as I thought. VA is evil. but they have a deal where if you show you spent at least $250 trying to fix it and it still fails then you get a Pass ("E" for Effort).<font face="Verdana, Arial" size="2">Originally posted by marcucci:
BTW, that's a pretty severe limit on emissions- here in the Dallas/Fort Worth area, it's 220ppm. Haven't had to do my 'lude yet, it's still too new. </font>
