[vectraman]

Hi my 2007 vectra 1.9 cdti has a problem , I went to start it this morning and it started but was misfiring and smoking badly,went to rev it and had no throttle so put foot right down on pedal and held it down and eventually revs came back , put code reader on It and no codes and it is also fuming abit could this be the egr but there is no codes thanks

More than likely EGR stuck open.....has the fault reappeared again yet?

Hi sorry yes it's done it a couple of times since but just stick foot flat down on throttle and it will rev up eventually

Boost leak? Turbo Vanes sticking?  there are a few other possibilities to examine before replacing any parts but look for a split in a turbo boost hose first (usually makes a noise which is either a whistle or if in rubber sounds like a farting noise)
