147 1.9JtdM Engine fault..
Hi, I have for some time been experiencing a bad start (plenty of smoke), basically a miss fire and rough idle, once the car has been revved a few times it runs fine.
No loss of power, idles steady, no massive amount of smoke.
When I got my last service at Auto Lusso I had the injectors tested all values were out but 1&2's values were furthest out.
I have since changed and recoded all 4 injectors, which has made very little if any difference to the problem. All 4 glow plugs were also changed previously.
I have now started noticing quite a loud diesel knock/tapping noise when accelerating if the car is under load, low first and second gear is where it is very loud and obvious. (this was not obvious, I certainly had not noticed it, before I changed the first 2 injectors)
I am yet to clean out the inlet manifold, should I do so? Is it likely to be making a difference?
Any other ideas of what this could be would be appreciated!
