307 missfire

Peugeot 307 SW 2005 2.0 16v t-diesel engine- rhr - missfire

There is a slight miss under acceleration and the fuel economy does'nt seem that grate at 40mpg. Have hooked it up to the snap on solus pro, but no fault codes showing. However when I go into the engine managment data ,and under fuel circuit information scroll down to cylinder injection flow correction %, No 1,2 and 3 cylinders show betwee 97-100% but No 4 cylinder is showin 66.3% - 66.7% when the car is running. When the engine is switched off No 1,2 and 3 show 0% but No 4 is still at 66.3%. Have previously changed No 4 Injector with No3 but made no difference.

Any help would be appreciated

did the reading of 66.3% move with the injector or remain at no.4 position

The reading did stay at No 4 cylinder after swoping both injectors in what I would previously of called cylinder 1 nearest to the timing belt but the computer has difference ideas.The reading on No. 4 does move slightly (up to 1%) when you rev the engine.

My stutter was egr with no fault codes showen .

I dont think its the injector then. My first move would be to go into pp2000 and do a global test for faults and then maybe on to something like injector parameters and see if they all agree on settings. along the line of injection flow on your post. Then reconfigure the no 4 cylinder if different
