300tdi misfire 3000rpm

touchwood · Jul 13, 2012

Morning all just after a little help with my 95 300tdi. It's started to miss fire at 3000 rpm when under load. It starts spluttering like it's running out of fuel then a puff of blue smoke out the back ( think it even make a cracking sound)

Intercooler pipes recently replaced, new lift pump 50 miles ago. No sediment filter fitted. Fuel filter seems clean. Air filter clean. I have also Recently changed injection pump.

Revs ok when under no load!

Im thinking injectors!

Any advice would be appreciated

Just a quick up date

It's not just when it's under load but it's more pronounced under load! Booked in in with local diesel specialist to check turbo boost etc.

It turned out to be a air leak in the fuel pipe going to the tank! All sorted now!

For reference for members reading this in the future mine was doing the same and it has been diagnosed as the mass airflow sensor
