nope....since i dont drive my truck that much it may be a while before i run gas through it...

 

The same coil that fires the #3 cylinder also fires the #6 cylinder. If it were a coil issue you'd be having the same problems with the #6 plug.

I would suspect a fuel injector problem, or possibly even a base engine concern (intake or head gasket, for example).

 

Have you changed the gap on your plugs yet? How's it running?

 

i am going to be re-gapping them tomorrow......my truck spent the last 2 weeks at my uncle-in-law's getting the rear end fixed......and replacing the plugs that the dealership gave me the wrong ones when i changed them in February......

i will have a reading tomorrow on what the milage increase is with stock gap and the Screamin' Demon coil pack.......

 

Sweet, I've been looking at these for a while now, and if you turn up some good readings it will deff. be on my list of things for the truck.

 

i dont know how much of a gain i will get........i can tell you for a fact that with the stock gap and the Screamin' Demon that the truck idles and runs sooooooo much smoother........

 

ya i wana know also i got some 80$ wires and autolite +2 or something and still nothing diffrent so maybe i can try this.

is it jsut a plug and play?? or does it need to be re wired places? and if it helps mpg then that is also good

 

the only difference is how the plug wires go on the coil.....and it comes with instructions...

 

LOL damn it I want results!

 

you will get results soon enough..............i will have a stock gap and Screamin' Demon result tomorrow.....or maybe later tonight.....

 

lol. I'm wondering if you'll wait to install the tuner until you've done the gapped tank of gas. That would be a tuff one.

 

yea that will be a tough one........i prolly will be able to run a tank out of it if i get up and gap them 1st thing and then go get gas.......i prolly wont get the tuner until thursday....

 

Any updates on this yet

 

nope....going out to gap them here in about an hour.....and then to get gas....

 

i actually will have to gap the plugs tomorrow......it is raining here and i have no garage to work in that is local......so tomorrow i will gap the plugs out to .065.....sorry guys to keep you waiting.........

 

no excuses! lol

 

So get gas now, and gap the plugs tomorrow!! I want results!

 

Gas station that is closed with a cover? You can do it there! lol

 

got the gas.....plugs tomorrow.....1st thing after work........

BTW.......UPDATE ON 1ST POST!!!!

 

Wow, can you think of any reason for the big decrease in mpg?

 

I hope it's due to the improper gapping for the new coil pack.

 

nope......the only explainations i can think of is:

1. Truck was missing the next day after i installed the Screamin' Demon....had NOTHING to do with the coil pack, it was that the dealership sold me the wrong plugs for the truck....
2. That the plugs NEED to be gapped out to .065" instead of left at stock gap......I wish i had time to run another tank of gas through her before the Bama comes in, but i dont think i do......I dunno i may drive her to work this week since gas is down to $1.95 a gallon here......

 

all the gas stations around me stay open 24 hours...

 

i thought about it more last night......could also be that big **** tire that is sitting in my bed blocking the air flow! lol that is the 1st mpg check after installing my spare tire mount with the 35 on it........you know, the air bubble that the Myth Busters said happened in the truck bed....

 

lol so your results really wont be too accurate.

plus the ambient air is different then your other mpg figures. and you have done more mods since then.
