Civic EG

so i just bought a 93 eg si witha grs swap and it drove fine for a couple days and now its miss firing baddd. my mechanic said that cylinder no. 4 has no compreshion ad he needs to do the head job with gaskets and that will fix it... but im afraid that it might have smt to do with the ecu.. anyone have any solutions????

gsr is what you mean i believe and in that case this should be moved to the b series section
any how as for the cylinder no 4 ask him if he added some oil to the cylinder too see if compression came up if he added oil to the ctlinder and compression came up its eaither bad valve stem seals or bad piston rings

yeah gsr=]
