I finally got her started today after a month of having her!!:doh: Anyway all is well, but just one thing. It's mis-firing bad and it will not rev above 2500rpm! done an ignition test all's good FP test, same! I have HKS plugs and i think it might be it(the problem). Any body had this problem before?:der:

Do a fault code check. 2500rpm is fail safe mode. Or is that what you meant by ignition check?

Could be an air leak or AFM problem not showing on the fault code check.

It wasn't broken. I was trying to get my Z32 to work.

You can try to clean up the connections before you replace it. Think your only looking at £40 or so to get a second hand one.
