i own a 1995 nissan serena fx rio 2.0 td automatic imported from japan the problem is it starts and runs a1 but as soon as it gets warm (normal on guage) it seems to lack power and starts missing and dies but will start up straight away when it starts missing plumes of smoke pour out exhaust but if you floor it it stops missing and smoke clears and its off like a rocket until you try to set off from standstill again when it is in park or neutral the engine revs up no probs new turbo fitted and new headgasket fitted after it blew it last time new fuel filters oil changed i cant seem to get any answers off any forums i checked the fuel cap for blockages (ran it without it on )still same when it warmed up im baffled any help please its driving me nuts
