Misfiring when cold
Hello all, first time user of the forum, hoping you may be able to help diagnose my problem!
I have 2014 F150 Lariat with a 5.0L. It only has about 60,000kms, it starts great and runs fine once it's warmed up but for the first 3 or 4 minutes it will misfire. It won't miss at idle, but if you push or tap the gas, it will miss.
My first thought is the coil (acts like my Ranger did once the coil pack went) or maybe a bad plug wire, but since it only has 60k kms, it "shouldn't" we the coil or if wires. Any idea of what else I may want to check?
On a side note, I haven't yet checked the coil or for bad wires, just want to gathee the info before I start digging in to it!
