Flashing SES, BAD COIL!!!

[KNBlazer]

This is more of an FYI....

At a stop, truck stalls, fire it up and is jugging, take off and SES starts flashing, at this point already knew bad coil, drove about 1/4 of a mile home....Scanned PCM, and dreaded P0300... unplug one coil at a time, and once I got to #4, no change in idle, whala... checked scanner and indeed P0304...replaced bad coil with my last used spare, and all is well.....the other coils are still factory, 199,335 miles...

Yup, sounds familiar. I've replaced two coils on my 2003 Voy.

I now have 6 brand spanking new AcDelcos ready to go in...

AT 200K, time for plugs as well, unless you swapped them recently like a good proactive owner would, which I know you are.

But of course I am....lol... current plugs have 10-11k miles on them... will only replace the bad coil spark plug, just received the plugs today, coils yesterday...
