Hi all.

Apologies for this being my first post but I have trawled Google and this forum and found nothing relevant..

I have an '06 GP 1.9 Diesel MJET.

It has recently acquired an injection issue with injector 2 running at -312.

I have swapped the injector, then swapped injector 2 and 3 and the issue still sits in injector 2 no matter which injector is in place.

No fault code shows and the engine management light has never come on.

I have also replaced the fuel filter, air filter and injector plug.

The car has a full service history with Fiat.

Please, does anybody here have any ideas?
 
Shaking? Like hesitation? Or kangarooing?

Ok, do you having a tuning box or a remap? Also when was the last time you cleaned the erg valve?

I have a remap, but I am having it taken off Wednesday to see if that helps. The EGR valve was cleaned a couple of weeks ago.

I forgot to mention that injector 2 does not show up on the coding screen of a friend's snap-on unit, only 1, 3 & 4. I didn't think they were coded injectors but it appears they are?
 
Ah.. Was it a live rr map or a generic guy ina. Van jobbie? (Aka brintech)

I bet that's your issue if I'm honest! See how it goes without the map :)

It was a generic map done by a man in a van (ecopower Doncaster). My brother owned the car previous and had it done so it was easy enough to find out who did it.

Thanks again for your help, will let you know Wednesday night how it went!
 
Hey mate. Did the map being removed help? I have the exact same problem with my 07 1.9. My friend who is the mechanic has given up and was going to buy a new ECU which I don't really want to fork out for. I don't know if mine has been re mapped or not.
