It is either something electrical or just flat out bad gas. I am trying to run it all out to see if that fixes it. Any ides???????
1) Stop dumping octane booster in; you won't help anything but may fry your plugs. I assume you have all 93-octane in there now, right?
2) How many miles on the car since you changed the fuel filter? Maybe it'* got some flow problems. I'm thinking more fuel-related than ignition-related problems here if you see some difference in performance when you change the fuel mixture like you did.
The fuel filter is under the car, inboard of the passenger'* side subframe behind the front wheel.
