Can you I've never worked with automobile electronics, so this might be totally off-the-wall, but ... isn't there enough leakage from the spark plugs, both as radiated and conducted interference for it to be picked up ? In other words, if you plug into the cigarette lighter, don't you see noise correlated with the spark plug firing on top of the 12V ? Can that be used ?
