I have a Fiat Ducato 2.0 JTD,
At 2350 rpm the engine will either cut out or go into Limp mode. If i then turn off the ignition for a few seconds and restart it, it runs again. I can drive it all day long, justg as long as I don't go over 2350rpm.
This only occurs when the engine is warm (ie the temp needle starts to move), before that it'll rev fine.
It also, only happens under load. If I'm stationary, it doesn't matter if the engine is hot or cold, it will rev to it's limit.
I have changed the EGR valve and just about every sensor, I have also put a computer on it which gives an error code saying ''Invalid signal from the Fuel pressure censor''.
Any ideas? It's driving me nuts.
