Re: Split-Fire plugs
quaterpound<br /> if your 250's are OX 66 the maint procedure is way different. if they are HPDI 250's then they have no O2 sensor but do have other quirks, make sure all the updates are done. when all are done there will be numerous white paint marks
. the first few years of the 250/300 had some "issues".
