well my truck had developed a miss. so i thought maybe i needed to route the wires correctly. i printed the routing off and went out and started redoing them. i even went to advanced and got 2 pkgs of wire looms to make sure they didnt get near each other. that didnt work. it still had a miss. even had a code the other day of a cylinder 2 misfire.
so i think maybe i have a bad plug.mind you i had this problem about 6months ago too.but i put new 3923's in it when i installed the new headers. had my truck jacked up and the fender wells out. easy to get to. and i took my accel coil off and put my stocker back on.because of all the horror stories i have read about accel coils going bad. just took it for grantit that it was the coil. those plugs only had about 3k on them. been using the autolite 3923.

so today i stop and get some stock champions rc whatever, i forget the number. only 1.99 each. changed them out today and it feels like a gained 20hp. the truck runs so much better.way better than the 3923's ever did. i will not be using the 3923's again. that set of 3923's looked really good too. they had a little over 2k on them.

i will be putting the accel coil back on tomorrow to see what happens.

 

would also like to add that all the hemi guys try to dog our older v-8's. let them try to change all of there spark plugs in less than a half hour. lol

 

They ain't got 8, they have 16.

 

edited. i new that. just wasnt thinking. i have just seen so many posts by the hemi guys on how changing there plugs suck, and take forever.

 

I ran e-3's and had the same problem. Switched to champions and runs better than ever.

 

hmmmm, may have to try goin to stockers, i run 3923s and my truck has a miss at idle

 

i got the Champion Coppers from the dealer ($28 for all 8) and they were WAY better than the E3's i had in it....so i agree the Champs are awesome plugs.

 

I've been using champions for 59 years in all makes of cars I ever had and have no complaints. Also used to wrench on others vehicles and it was left to me I used them in every thing.

 

You paid the dealership for plugs?

 

Haha thats funny dude. I remember when you used to vouch for the E3's....but yeah I have also had misfires from E3's and then put in the CHAMPS plug and have never had a problem since.

SIDE NOTE: I wanna say that the Champion brand spark plug is only plug I have heard of that has never had a misfire on our Magnum engines
