[QUOTE="Kevin Palmer, post: 917262, member: 54263"] First, anything is possible. That said, it is not probable... I believe you are going to find that the code you are throwing is a true/legit fuel to lean error. The O2 is coming back with the code as it is in fact seeing to much air in the air to fuel ratio. My next suggestion will be the upper intake gasket, which is testable using propane. As I said, I have seen the SD coil pack throw this code but MOSTLY with Job 1 applications. I just feel you need to get to "base" engine application before you do too many things. You can always throw it back on if the code comes back... [/QUOTE]
