Not sure what I will be diagnosing, I have had this ongoing problem with my car all year. I have changed everything except the drivers seat.
Problem is this.
In 3rd and 4th gear around 3500 to 5300 rpms the car sounds and feels as if i have lost a cylinder, (this occures at WOT) I have to blip the throttle or the clutch to get this to go away but that sometimes does not work, this also happens at any time and nothing in particular. It goes away at certain rpms and will continue to drive fine until it wants to kick back on.
I have put in bigger ground cables
Brand new dizzy
new fuel pump-filter and gas tank
new plugs and wires
new battery
msd ignition
fuel pressure is fine never drops off.
As far as location of dyno, it does not matter, I will drive to ohio or Indy if I have to( dont want to though)
Thanks again
Devin
