[DRACO A5OG]

Not for Nothing, but how is the Dizzy, remove cap and see if there is any slop on the rotor, up and down and or axial. I had miss fires when my dizzy's internal bearing wore out.

If I may suggest try not to put other DME's into your car, if the fault is your car, it will damage the DME. Which performance chip was it?

Low rpms bucking is usually the characteristics of an OEM chip

or, a long shot

Have you replaced the fuel filter?

I am sometimes in the area, if you like I can swing by and test your DME in my car.

PM me,

Jim
