Hi guys, my VN in random ocassions it starting kind of rough.

It been a while since this started to happen and after a few visits to get my oil change on Pepboys the service team communicated that the battery was pretty low on cranking power, at that time I was thinking that the battery was the issue but recently at last I got a new battery pretty much the sameone H6 with 760cca and randomly had done the same.

I already have the HPFP from Sharkracing that is suppose to be the one from the Sonata and HKS spark plugs that must still pretty decents. I read about some people having issues with the injectors too. No CEL and this happens randomly.

Any direction to stop those weird crank start up?

Sorry for my english is my second language.
