3.8 #1 misfire on my grand caravan

I can test the coil pack. Maybe the injector although it will be a pain.
Lol at knowing which cylinder is which. Couldn't replace coil pack or wires very well if I didn't.
Wouldn't be bad to change the intake gasket regardless. The timing chain set is on my to do list also. Van has over 225k on it easy. I put about 150 miles a day on it or more.
When I change the gasket I'll have an injector on hand just in case.
If these don't work them I'll change part of the wire harness as I've heard these are a common failure when all else don't work. I'll report back when I'm done. Might be a few weeks. Money has been tight lately due to the dart having issues and picking up a ticket and a vet bill due to my dog.
Thanks for the info . Feel free to add to it
