Morning everyone I have a 2004 Rangerover it started running extremely rough. I pulled the codes and it was showing a misfire for every clynder besides number 1, a down stream 02 code and the evaporated purge valve code.

I pulled one of the coils out and the boot was covered in oil. So I replaced the valve cover gaskets and grommets, sparkplugs and coil boots. Started it and it had two misfires that would follow the coil. So I replaced those two coils. Now all parts are from landrover no aftermarket.

She ran good for about a day and started running extremely rough again and if you bring the engine off of idle the engine light constantly flashes one second pulses and I have these following codes
P0302, p0305, p1300, p0304, p0443, p0036,

Number 5 is one of the new coils. What worries me is every other vehicle I have worked on that has had the engine light do the constant flash it's been a timing related issue but I'm not getting and codes for crank/cam out of sync

Any advice and suggestions would be greatly appreciated

Thanks
