Breaking up...

[Clipse]

My car has never done this before and I hadn't changed anything for a while before it started. It breaks up under boost and when I start off from a stop. It deosn't do it every time , I'd say about 50% of the time. At first I thought fuel cut, but there's no way at 15 psi. I tried tweaking the AFC anyway and it made no difference. My plugs are fine, brand new actually, and the wires seem alright.

Help me out

More info. What do you mean "breaks up"?

The rpms break up, just a sudden loss of power...like you hit fuel cut, but repetitvely.

Sounds like an ignition misfire.

I thought that but ruled it out because it seems like that would happen at all rpms.

Ignition misfires will often only happen at higher load (full boost, especially at higher rpm or the torque peak).

Plug wires

Check your plug wires, and your plugs. I had the same problem, replaced them, not its fixed.
