Yea plugs is next move in terms of parts. I should pull the plugs to check for proper gap although I would like to think that ford would put properly gapped plugs in their motors. I'm gonna send 5 star tuning my data logs and see if they see any issues in the tune
I am aware of 5 stars warranty, kinda intriguing but keith from oz tuned this. I have not loaded the oem tune. I mainly wanted to see if anyone needed to change a pack since I've already replaced the wires and the issue is still present so it could possibly be a tuning issue
What's up guys, my 7.3 (most times) will start misfiring at higher rpms around 75mph and up. Never misfires at idle or just regular driving. I changed the wires with good wires but it's still happening. Has anyone else experienced the wires not being the only problem?
