Well, I thought I had it fixed but only improved it marginally. In a nutshell, it's missing on the dyno. It's not plugs cuz cylinders 5-8 are rich and 1-4 are fine, done this on 3 different brands. It's not the coils on my Delteq cuz a couple of the coils share good and bad cylinders (eg: 4 and 7 are on the same coil with 4 fine and 7 rich). I don't think it's wires cuz they're not burned and I wouldn't think a cheap wire would cause such a miss. Voltage is 11.8 under load on the coils so I am gonna try to hotwire them to the alternator to boost voltage to 13+ and see if that doesn't help. All that's really left is optical. Don't think it's fuel cuz my AFR is completely flat under all tuning conditions. If it's 13.0:1, it's flat and if it's 12.2:1 it's flat. Thoughts?

Replace the wires anyway. A cheap wire can't cause a miss, any wire can cause a miss, especially if it is the one's you put together yourself. I have a box of bad wires that look brand new. If it is not the wires, go after the ignition. You must change parts until you find the answer.

 

Well I guess you're right. I just hate spending money and not solving anything. BTW, I have friend that lives in Lincoln Co. Mississippi. If I remember, Amite is just south of Kentwood right?

 

Tried hotwiring the coils to the alternater for a voltage boost. Still misses. I need to check and see if the back cylinders are burning any cleaner though.
