Freelander 1 TD4 engine problems at 1000-2000 rpm´s
 

Hi
I have a 2004 TD4 Freelander with automatic transmission. It has begun to act strangely at between 1000 & 2000 rpm´s where the engine runs uneven and splutters. when it runs above 2000 rpm´s it sounds and acts normal (as far as i can tell) and when it starts up and runs in idle, it runs even 99% of the time.

It has started to run uneven a couple of times in idle as well though.
Fuel pump is relatively new, and it doesn't come up with any error codes on the computer when plugged in. Thats to say it popped up once out of a bunch of tests with an error code 1613, which i can´t find any explanation on.

Have anyone had similar problems or have an idea where i should start to fix this problem ?

Best regards
Jesper

It was the fuel nozzles - ended up changing all 4 nozzles after having them tested. problem solved
