So here's my p0306 issue.
This past weekend I went to barstow, on my way back I notice a decline in power and my check engine light comes on for no damn reason
So I run my scangauge and it's p0306. I call up s10killer and fddriver and they tell me that it's Cylinder 6 misfiring. I pull over at the nearest Vatozone and get a new plug. Pull over at a friends house and let my truck cool down then swap it out. All is well and I head to the casino.
Today on my way to work, check engine is back and better then ever. Running same p0306 code on my scangauge.
What should I swap next? Coil pack? Wires? The wires are only about a year old and the plugs were done about 3 months ago.
