Hello all,

I have an problem with coil C according to the codes. The interesting part to this is that I just had to tap and insert a new plug and coil on C after it blew the threading. The process to tapping and inserting the sleve was easy enough, didn't seem to have a problem with it. The Plug and Coil are new and when I start the truck it doesn't seem to be a smooth idle. On a test drive I find the engine sputter when accelerating.

Here's my spec's:

97 F250 5.4 liter

I could use some assistance. Thanks ahead of time.
