Hey guys, ive read a few posts about misfiring but mine seems to be different.
So basically, my car misfires on start up, really bad idle. the misfire is through the whole rev range boost or not. sometimes it goes away randomly then runs smooth for abit and comes back.
ive got splitfire coilpacks that the previous owner changed, recently changed oil to castrol edge titanium 5w-40, k&n oil filter, z201 fuel filter
i took it to nismo performance and got a diagnostics, they said there wasnt any electrical problems and said it was mechanical.
i changed the irridium spark plugs because there were old it ran okay for a few days then it came back and it has seem to have gotten worse. so i changed then back to irridium because they seemed to run a bit better.
thanks in advance, josh.
