Rb20 Missfire

[julzy71]

Hey all,

Have a ridiculously annoying issue.

My r32, rb20det-cooler, exhaust, 555cc, emanage.

Now the issue is with number 6, and number 6 only.

The car runs and starts fine, happens hot or cold and goes away when boost or load is introduced

It has brand new plugs, have checked coil packs, resistor pack, igniter, injectors and nothing.

Everything is fine and within spec.

I pulled the cam covers off, cams still have lobes on them and valves are stiff.

Oscilloscoped injector and coilpack pulses, are at the right time and all the same voltage.

I have no idea what to check next, it has spark, fuel and comp.

Any suggestions??????????

thanks
