Did Time-sert spark plug repair, now truck is missing badly
I had the number 2 plug blow out the other day, I put a new coil back on it and installed the old plug back in, I could tell it was wasn't threading right, , so I barely snugged it and drove the truck home, ran perfect. Found out about the repair kit, borrowed it from a friend and we did the work yesterday. Everything went well, installed plug and coil pack, now it will barely run. I know that it's the number 2 cylinder causing the problem because I can unplug the number 2 coil pack and the miss doesn't change, any other coil pack I unplug while the truck is running makes the miss so bad the truck almost dies. I have swapped the coil packs around to ensure my new coil pack was ok and that didn't help, put in a new plug, still the same. So, is there any way I could have damaged something by installing the kit? Thanks in advance. I really don't want to pull off the head!

You have to ID the failure as either ignition or fuel.
Remove the injector plug so fuel is not injected into the cylinder while testing..
Test for spark with the coil or wire out of the hole and attached to a test spark plug. Start the engine. You either have spark or not/very weak.
Is plug boot setting on plug and not off to the side, in the hole?
Next is testing with a stethoscope to hear if the injector is operating by compairing with another.
If the injector is totally blocked, it is more difficult to tell for the owner except by smelling the hole with a sample tube.
A dealer tech has other ways to tell with his equipment.
You have to see the fault because there in nothing else to look at except the PCM and I would doubt that is the problem.

Sorry, I guess that would help. It's a 99 F-150 with a 5.4L. It is getting spark and fuel, tested that last night. Tried a new plug, didn't help. I talked to the guys at Time-Sert today and they said that I probably did one of two things, either did not get the insert seated properly, not allowing the plug to sit down far enough, or I actually reamed into one of the valves. I am going to do a compression test tonight and see if that is the case. Any other suggestions will be helpful. thanks,
