Just picked up a 1990 240 hatch today and am already finding little issues. One being not so little. The car runs great, but, sometimes under WOT ONLY, it will missfire some and backfire.
Engine is just a bone stock RB20 still using the stock tune.

Search search and search. There are hundreds of threads about RB misfire issues.

If you don't care to search the jist of it is stock RB coils are junk, do a LS2 coil pack swap and be done with it. Or you can keep fucking around with getting coils from VH45s, electrical tape or trying to seal the coils.

Okay I will poke around, sorry, I posted through my phone at first and the search tool is not phone friendly. I will definitely look into the ls coil swap and see what else.
