Engine stutters,hickups.Gets better with power consumers on...What's wrong ?

[AWH]

My 2 gen Prelude engine stutters and hicksup, almost undrivable by now.
I found that when i put on more power hogs/consumers,like turning on the lights,the heaterfan,the rear windowdefroster,etc. it gets better to practically normal.But ofcourse that is not as things should be.Where do i have to start looking ? Could it be the regulator,or do i have a short or something?

I read about a main relay under the dash that can fail,could it be that and does a 2gen.Prelude have that relay ?

Can somebody put me on the right track ?


Auke.

EDIT : Fixed already : ignition module was toasted.Happy driver again.
