#1 misfire, #6 misfire, and a mystery coolant leak
Alright, I've searched and can't quite hone in on what my issue is. 3 days ago mey "Service engine soon" light comes on. Took it to Autozone and throws the following codes
#1 misfire
#6 misfire
Random misfire
I popped the hood and somehow the #6 wire had popped off. (All plugs and wires were changed approximately 5k miles ago) I went ahead and replaced both plugs #1 and #6 even though nothing seemed out of the ordinary.I'm still getting a misfire...at idle i notice a miss and when i reach about 50-55 mph. Other than that all the shift points are fine, but thats where i've been able to duplicate the miss.
Additionally, I don't know if this is a related issue or not. I noticed a small coolant leak and was able to pin point where i thought the leak was. I fixed it and its dry as a bone now, just a loose hose coming from the reservoir.The reevoir does not leak until it is empty but leaks until past the hose that runs from the expansion tank towards the throttle cables. Obviously I can keep filling it but it does concern me that i can't find where the coolant is going. I also wasnt sure if there is any relation to my misfires. Any help or links will be appreciated

If you google "multiple cylinder misfire" the first couple of links will tell you about 10 different things to check out. Same as any other vehicle; ignition- good spark plugs, electrical continuity of wire/ lead, voltage from all terminals of the 2 coil packs. Air- valves in working order, no vaccum leaks, equal compression throughout all cylinders. Fuel -at least 30-40 psi at the rail, injectors clean and operating efficiently, good seal at O-ring. Check everything. I read on another board where some idiot checked for spark and had it on the one cylinder/plug/wire, so he assumed that he certainly must have a spark on the other 7...like its a dang Briggs&Straton push-mower. Noo, you don't stop at 1 spark plug LmAo!

Have you ever seen or read about the KSeal? Its a super-small bottle, I don't know maybe 8 ounces or so. I had a really, really small intermittent coolant leak from the back of the engine so a friend gave me the Kseal to try out. Shook the hell out of it, used only half the bottle, drove the truck for an hour and it worked. If you can't find the leak, you could always use some of this and probably be done with it. Personally, I would rather buy new parts and replace what is at fault, but since I didn't know what exactly it was and didn't want to drop $500 a couple months before Christmas and 5-family members' birthdays, I went this route and don't regret it one bit.

UPDATE:
Replaced both coil packs bc it was such a pain in the a** to get too. All was well in the world for about 2 weeks. #6 misfire came back. Wire went bad. Swapped out the wire and we're back to good. I've found the leak, tightened the clamp...at this point its not leaking enough to make me want to fool with it. May try that K-seal stuff out if I think about it. She's up and running good as new now. Thanks everyone for their responses

Same misfire issue - #8 only. New Kingsbornes a couple months ago. No leak. Changing coil packs and wires (again).
Any problems disconnecting the coils? Is there a wire clip or just snap on for the connectors? I'm pulling the plenum but not sure how fragile the connectors on the coils are.
