Hi fellas, Recently refreshed a 300tdi that had been sat for a while. New fuel pipes, lift pump, filter, serviced injectors.
The problem I'm having is an bit of an erratic idle. It starts fine hot or cold but will almost stall afterwards (maybe 300-400rpm) before it brings its self upto speed with a quick tap on the throttle after about 10 seconds. it then idles a bit high at 900 rpm and it occationally falls back to the low idle (300-400rpm) if revved. once again this is fixed with a quick tap of the throttle.
Ive tried fiddling with everything people normally say and I am fairly happy I dont have an air leak etc.
Any ideas?
The only thing I can think that is perhaps the auto advance mechanism is stuck because if i retard the pump it helps a bit (but puffs out white smoke)?
(it drives and pulls great and no smoke when running normally)
exactly the same as this guys issue
