[QUOTE="QtrFlsh, post: 16023011, member: 54955"] Thanks for the replys. It does appear that I am running a number colder than stock, even though they are denso iridium. Fuel stabilizers and a few longer-than-normal intervals between drives certainly doesn't help the cause. I guess the big deal to prevent pre-deonation when I got that pulley back in 04 was to also go to a colder plug. I did dyno tune it, and even currently run an wideband A/F guage as well as fuel press. and both are where they need to be (except now that a plug or two has fouled!). I'l go back to the 6 range this weekend and report back...I'll ohm the coil packs as I pull em out as well. Does anyone know the actual Denso part number right off hand? Any suggestions on a good gap setting? I used to use PSP back in the day, but I know he has moved on.... Thanks again! [/QUOTE]
