My 3.0 used to do that when I was pulling the hill to get home at highway speeds. Got home one night and opened the hood with it running. Man it sure was pretty watching all the blue sparks jump off of the plug wires when I revved it.

Speaking of that, have you done an ignition tune up yet? Cap, rotor, plugs, and wires?

 

sounds similar to my 22re but i only get code 14

 

You need to start your own thread for this~

 

yupp, that was the problem, new cap, rotor and another new wireset (dont trust the duralast ones, havent had em 6 months and they were already arcing off the boots) got it running perfectly again..

 

Glad to hear you got her running right!

 

yes I also got mine going because I didnt think it was plug wires now no stumble or miss / thanks to all the info and trouble shooting on this site . Thanks

That explains the AFM codes...I bet that's where the spark was grounding. And OEM ignition parts are the only way to go.

Forgot about it until now, but I remember having a similar issue a long time ago after installing an MSD ignition module with a 50,000v coil. I remember touching the AFM while the truck was running and getting a 50 thousand volt arm massage. Numb to the shoulder for an hour lol.

Glad ya got it figured out.
